There was a guy on here looking for comstar rotors- you might pull those and save them... Otherwise nobody really wants the comstars. I'm using a set on my F2, I think they look pretty good all cleaned up.
The cush rubbers would be worth saving too, if they're still good. Sprocket carrier will be the same as 77-78k, with the 10mm offset- Chopper guys like those for running wider rear tires.
