Replacement fork for a 1984 Trek 760
This could have gone in the frame builders forum but it is a mechanical issues and is in the mechanics forum.
Well I picked up said frame with a number of parts (vintage Campagnolo) with a Giant steel fork (unicrown, CrMo). It weighs a ton is not what I think should be attached to this fine frame. My thinking was carbon but I am open. Since I don't know a lot about forks, other than material, steerer diameter and thread or threadless along with dimensions (38 offset?) for this frame, I am here seeking learned recommendations for consideration.
Part of the parts list includes a Campy SR headset that is in really good condition but I am open to other headset options including threadless, but not too excited about that idea.
Ideally, a direct replacement fork would be good but what likelihood is there in finding one of those! Would a 610 of the same year have the right dimensions (47 offset?)?
Since it was produced with Suntour Superbe group, I will likely hang Superbe Pro parts on it.

Edit: 1984 760/770 fork rake = 38mm, so does not match the 6xx series.
If you do decide to go carbon, I've used a 1" all carbon threadless fork on one old steel bike. It looks OK, primarily because I (pure chance) did not choose a fork with really wide blades. So although it's a little out of proportion to the skinny steel, it's not horribly out. We've all seen some that just look so misplaced, and some of those were factory.

I think @Chrome Molly would have an informed opinion in this venture.

I have used the Nashbar threaded carbon fork for about 4k miles and find it smoothed the ride and eliminated some of the twitchy nature of the original. It may not save you much weight since it has a steel steering tube. If you want to retain your quill stem it is a good option. If you go thread less then wiggle has a Columbus fork that is all carbon and would save much more weight. We're I to do it again I'd have a steel fork made by a local builder. Nothing rides as well IMO as a well made steel fork. It wouldn't weigh any more than the Nashbar fork really.
