Maybe find a likely bike of similar vintage on CL and pull the parts. The leftover frame can then recieve whatever old maybe heavier parts that you have on hand and be sold on to someone who can use it. (sell a bike like this on the cheap to keep good bike karma going...)

I did this with a Shogun in order to get some good 100/126 hubbed wheels for my Panasonic. Haven't sold the Shogun, since the frame would be pretty cool for bike polo, which I've wanted to try.
