Every one wants more info for that old truck, but some times it is hard to come into. Well I found out awile ago
that GM offers a free, yes FREE, restoration pack for your truck. You get specs and info on the trucks produced for that year,
also restoration parts suppliers list.
You have to get the VIN# for your truck and call them with that # and they mail out a packet to you. So if you
don't have one get one..And this also works with most any Chevrolet truck or car you may restore..
