Hi Jim, just ran across your thread - very cool. I bought a '68 GMC Custom last summer and continue to play with it, so your post is very informational. She has 106kmi original paint and interior with 355 Chevy, L-79/041xhds. etc. Vintage 60/70 factory High Performance with th400/Dana posi. Like those wheels - will try to find some... Best, Bob - Seattle
