While not MV specific, there are a lot of parts that would serve well on a lot of MVs, without the MV Vendor markup.

Hose clamps looked OK, a lot of the wiring stuff looked good. The ad section at the end give a lot of good places for gauge resto and such. The drive rivets, split rivets and a log of the cable hangers are also worth a look.

Another one... more modern stuff.. but it has tons of illutrations to match up what you got with what you need. The catalog is great... but again, not completely MV specific (although they did list footman loops and a few other items).
