I can't completely help you since I've never done it myself. But I can tell you what I've been told. If you plan on using a mechanical style clutch, the original style the Elk would have you'll need it all. Bellhousing, flywheel, clutch fork, the shifter and all the linkage, pedals, probably crossmember and possibly driveshaft. If you plan on using a newer style 5 spd most of them use a hydraulic clutch, therefore you'll need a different style bellhousing for it. I've been told for this you can use a V8 F Body (camaro) one. Again I'm not exactly sure this is just what I've gathered so far. Someone else on here should be able to help you a little more with the specific's. Anyone? But if you did find an original complete manual trans setup. That's a pretty rare find and some people would kill for that fork. Pick it all up. Even if you don't end up using it I'll guarantee someone else will.
