i want to know if chevy put a straight axle in the front of a 85-98 or 88-98 chevy 3500 HD 4x4? Or they even made a 3500hd in those years? because i am looking for one to make a lifted truck, i know i could just put axles in but me and a buddy had an argument if they put straight axles in those years 3500 HD's. oh yea and what years did they put the 6.5 turbo diesel in trucks? i need to know that too i said 94-2000 but i could be wrong.. thanks a bunch guys!!!
