Can you tell us what parts you need? Pretty much everything is available
somewhere, and there's even some reproduction stuff out there.
See Rob Groves' site at
http://www.cmp-resource.com for the latter.
Reproduction manuals are available through Alex Blair at
http://www.geocities.com/MotorCity/Downs/5024 .
A lot of engine parts are still available commercially.
Let us know how we can help... where are you located, and what type of carrier do you have? If you have scanned pics, you can attach them to your post... but if you'd like to get into a general discussion on carriers, please start a new topic in the Carrier Forum!
Cheers,
Geoff
