An article and list of where and how to find used pre-1973 GM truck parts.
http://sites.google.com/site/woogeroo/Home/19601966ctis/usedgmtruckpartsI have recently tweaked, rewritten and edited an article I have had on my various personal web spaces for many years about looking and searching for old chevy/gmc truck parts. It is not the end all explanation to finding the holy grail you may be searching for, but it could be very helpful to some folks. I am not an expert by any means, I am just sharing what I have learned or found out.
Enjoy,
