[oldno7]

Let me start by saying i hav forgot how to post pics so if some one want s to pm me and offer a num so i can text them pics and they can put up pics for me this would help alot. So anyways i ran across a gmc i think 94 4x4 1 ton I would love this truck , because im wanting to convert my 67 ton to 4x4. I had always heard that the 73-87 was a perfect setup so this truck has a wheelbase of 131.5 did they shorten the wheelbase in the late 80's and in the 90's
