It is steel. That's an interesting option, I've got a few friends that weld. I'll ask. I would love to keep the frame - my wife has loved it and they're not making this model anymore

Devastating, yes, life threatening, not likely.

I'm sure some will disagree, ugly is not necessarily scary. Looks to not be torn or cracked, very likely this can still be ridden off into the sunset as is. Bondo it, braze it, fill it, whatever. The stud welder will make a mess if the ding doesn't want to pull out as I suspect would be the case.

Huge bummer.
Is it steel?
If so, coming from a car background, I wonder if a stud welder gun could improve that ding. It didn't take much to put that ding in it, so it wouldn't take much to take it out...
Maybe stop by an independent shop and see if they can take a few pulls on it? Maybe worth throwing $100 at if the bike is a keeper? It will need some finish filler and paint, but it already does....

The aluminum straightening blocks are pretty cheap, and worth a shot for this in my opinion.
They can be found by scrolling down on the frame building parts page here.

My wife rode it to work without even noticing. I discovered it while putting it on the car's rack in preparation for our first ride in GNP. It felt like a gut punch seeing it and I can't deny getting upset... but no divorce was threatened . She rode it without incident. The frame still seems straight and she can't detect any differences..

Yes, This might require refinishing for an invisible repair, but IMHO this frame would be worth the effort.

So now what? Send it to @gugie and have it fixed, he can do these in his sleep and a fantastic job as well.
I'm out of town and only have this bad instagram picture to show the crack.
I was wondering if it would be worth while to get a donor frame or just search for a new dropout. I was able to find a frame on eBay that has different tube damage that has the correct Suntour Gs dropout. I've looked on eBay but haven't found a single dropout for sale.
Before I found the damaged frame, I was considering buying a set of Campagnolo 1010 dropouts, getting them installed. Then getting a place out west to spray some imron paint in the same color.

I actually don't know what I'm going to do. I don't know my options to be honest. So far my plan is to make a display mount for the wall in my build living room build it up with some Suntour Superbe and not ride it.

Alright guys, I found another Columbus-tubed one.
This one was listed cheap on the local CL as a Trek 912. Since there is no model by that number shown on the Vintage Trek website, I needed to take a closer look in person. The bike was being sold by the original owner, including the original sales receipt and owner's manual. I was disappointed to find out that the owner actually wanted more than twice the advertised price, insisting that his daughter had misinterpreted his instructions for listing it. The finish and graphics are in terribly shape, with no hint of any tubing decals anywhere. The owner didn't remember what kind of tubing it was made from, but it's a very lightweight bike. He paid extra for the Jim Blackburn rack, Zefal pump and toe clips. He also noted that he replaced the wheelset somewhere along the way. I was a bit skeptical about the model number despite confirming that's what the original shop sold it as on the sales receipt. It wasn't until the owner agreed to let me pull the steerer that I agreed to buy. We haggled a bit, and it came home with me.
The sales receipt is dated 3/28/80. However the G4F8 serial number corresponds to a 24" '78 TX700. This is why I was skeptical of the "912" model designation. Incredibly there's a dove stamp on the steerer. My guess is that the original shop received this as a bare frameset, and wasn't able to sell it for a couple years. The groupset is unimpressive, corresponding to those shown for model 412 in the 1980 Trek brochure. The shop that originally sold the bike is a reputable one, and well known locally. I would surmise they cobbled the model number together using the frameset specs and the parts they built it up with. Whatever model assigned to it, this is yet another example of the serial number on an early Trek not telling the whole story. I would call it a '78 TX770, based on info on the Vintage Trek site.

Indeed, a dent like that will not affect the ride, and may not affect the longevity.

This is just the kind of work frame guys like Andy Muzi @ Yellow Jersey do very proficiently. And they can often tell a lot from enough photos, sharp and clear enough, from enough angles. I'm not familiar with the builders out your way, except possibly for Mark Nobilette in eastern Colorado.

Soo on my 1980 412 I have the micro adjust headset I’m wanting to replace it with something more easier for me to use. Does anyone have any suggestions?

I had my ‘82 614 crown race seat and head tube milled/reamed/faced from JIS to ISO standard so I could open up my options for replacement. Still in process building, but I installed a Tange/IRD Rollerdrive.

My 1983 Trek 760 with upgraded Campy crankset and wheels with Campy hubs, and Shimano SPD pedals. I'm going to restore her back with the original Suntour pedals and crankset but keep the upgraded wheels because I gave away the original wheels with Suntour Superbe hubs. This old gal has stuck with me the past 36 years. She waited patiently for me for 25 years in the back of my garage while I got married, raised kids and played basketball and found other loves. 8-9 yrs ago my buddies all got back on the saddle and started riding again (on new carbon bikes). I looked for her and regreased all the major components, got new tires and new shoes and pedals and joined them. The rest is history - I'm into carbon bikes, single speeds, vintage bikes, mountain bikes now! This gal has been with me on rides from Santa Barbara to L.A., L.A. to San Diego and back multiple times, Rosarito Beach to Ensenada multiple times, up and down PCH, up and down the river trails in SoCal, around the Rose Bowl, around the streets in the SGV. I took a few tumbles with her, but I sacrificed my body (lots of road rash) to protect her.
I will never let her go. She waited patiently for me. If she wasn't there waiting for me I wouldn't have had a bike to ride to join my buddies, and may not have gotten back into what is probably my 1st love - bicycling!
Edit: I was unemployed and kinda down 8 years ago when I got back into cycling. I didn't have the resources to buy a new carbon bike to keep up with my friends so my Trek 760 allowed me to get back into cycling quickly. Fast forward 8 years and now I'm buying bike parts left and right, building vintage bikes to allow me to relive the 70's and 80's, when I was a teenage and young adult that loved bicycling.

I've passed on a few in the past, but this time figured why not. 1982 412. Went off of a non-drive side photo and paid $125. Surprised to see the Suntour Blue when I picked it up. Bought from original owner and he obviously took excellent care of it before storing it the last few years. After calculating the possible upgrades on the drive to get it, I talked myself into leaving it alone on the way home. It probably deserves to stay original - or put back in a freezer bag. This bike is why I will never buy something with bad paint. You shouldn't have to. I counted 3 chips to fix. New tires and tape and she'll be all set. The crappy lighting and pics don't do this one justice.

That bike deserves the BL group. Beautiful, nice work.

I saw Victor walking to the company I work at and he was running late and did not have a car. So I gave him my old Trek so he now has a way to get to work without walking 40 minutes one way.

^^^^^^^^ In the Dictionary of American Expressions, there should be a photo of that ^^^^^^ frame in the margin next to the entry for "Rode hard and put away wet". I'd like a hit of whatever that seller is smoking. We've picked up complete or near complete all-531 Treks from that era, in MUCH better shape, for half that.

It's an '85 470, which is basicly a 460 with Shimano 600. Tru-Temper tubing I think. Low-mid level on the scale. Priced kind of high unless the paint was near perfect.
