Tim,
I have been searching all over the place and cannot find any decent parts suppliers catering to the deuce and deuce-and-a-half crowd. That doesn't mean they're not out there, just not an easy find!
Hopefully someone out there will know of a company that can help. In the mean time, try contacting
American Classic Truck Parts or
LMC and see if they can offer any insight.
In the mean time, like I always advocate, get with your local classic truck or car clubs and see if anyone there has any contacts that might help you out.
Mac
