i appologize for not replying sooner because i couldn't find it, i know a 1/2 ton is not the greatest but its a start i'm going to look for bigger axles and the frame can be strengthened but biggest problems is if i wanted to go to a 3/4ton 1 ton frame is that i'd have to find an original for this truck thats 4x4 or find a suburban frame that is of those tonages because the frame that i have under the truck is a 78 suburban frame
rdavid- what parts would you sugest i look for i would like to keep my setup the way it is just a diesel engine instead of gas and my t-case is married to the trans (the drivetrain is all 78 +/- a few years) just the body is a 64 i'd go for buy the parts that you have but there is a few problems i don't have money available for it right now and sidney b.c. is a ways to drive with a pickup (have to save a ton just for gas) but i would like to know what would you recomend i should change or what is the best to go for
thanks
Nate
