370 parts

So I just brought another 69 alpine 370 home and I could use a few parts:

- aluminum exhaust tube (this one's worn where the muffler rattled around on it)

- recoil aluminum hub - I think these are a little bigger than the regular singles... no?

- carb air box studs. Need to fit an HD carb

Pair of tracks... same old 114"

Thanks for your help
