A bunch of the parts on my 1990 were chewed up and replaced, so I decided I was going to go with M900 XTR/M730 XT/DX/MT-62 Deore and IRD brake levers. It turned out pretty cool. (I keep saying I'm going to swap out the cage on the XTR derailleur with an M735 cage... but...)

If you have the intention of using an M1000 as some sort of tourer you would need a more purpose driven gear set than a modern road set would include- specifically the low end. If you throw a road group on it, the bike is really too heavy and lax for that type of riding. It's not light and lively- but it's what it needs to be to haul a load all day. The beauty of the old frames- ESPECIALLY the STB Miyata touring frames is that they're sturdy, stiff, beastly frames- without being excessively heavy. The "Luxe Touring" iteration throws down some of the best components of the day- XT and 600 and Deore/DX shaving of weight and increasing cachet. If you look today, the big tourers are rolling with Sora- and the frames are tanks. There's not even the attempt to make them luxurious, prestige laden machines like the M1000LT was.
Have any suggestions for a cheap rear- rack?

This is also exacerbated by the oval biopace chainrings, and the 28 small is VERY oval. Proper rd function and chainlength is a must, and even then, at certain cadences the chain can get a rhythmic bounce.

Switching to a smaller front ring to get a lower low gear also can be a problem. I put on a 24 tooth and with proper chain length, I can use 5 out the 7 on the rear cluster and avoid the chain hitting that protector. It is probably a good indicator either way of a proper setup so as not to have such a slack chain in the first place. Before putting on that 24 ring, be warned that the FD won’t really accommodate it as I found out. There are posts about that here.
Hunh!
I don't have a 1000, but my 610 originally had a loop, which a previous owner cut off, Now I know why!

So is there any truth to the Miyata 1000 and the Univega Specialissima sharing the same frame?

Yes and no.

Same tubing, same angles (so I've read), different lugs/cutouts.

The wire loop on the chainstay is a common feature of Japanese touring bikes of the 1970s & 80s. As mentioned above, it protects the chainstay from chain slap. The other common way this was done is via two small braze-ons about 12" apart that attach to a replaceable rubber chainstay protector. I have also seen a thin strip of aluminum sheeting used instead of the rubber protector.

Looks like a great restoration project. The miyatas from that era had great style.

Same, I’ve never actually had a bike with one of these. Seems to be that they work well until they break, and I’ve seen a good amount of broken ones. Makes sense with how thin it is and that it’s protruding. I’ve also seen a few on this forum in which some owner along the way had no idea what it was and sawed it off.

Others probably have a better anecdote though.
