I am thinking about buying a 92-or-so GMC 4x4 from my uncle, and of course the first order of business is getting rid of the IFS. My question pretains to the front axle. CAN a GM 60 front be used if I have a passenger drop tcase? The automatic in the truck is toast, but I have a 700/205 (passenger drop) and can get my hands on a GM or a Dodge 60 much more easily than a Ford. What are the issues involved here, or should I just sell the passenger 60 and get a HP Ford?
