Thanks everyone for your input! I also found a 12bolt rearend and matching front from a guy that was parting out an old blazer I have a with him for both axles and an SM465 he had for 440$ ..Yeah I would rather keep the truck all GM, pretty well every parts store here knows my truck and has it in their computer! ... and I knew I'd get hounded for the slang LSD terms.. sorry im a GM guy and thats his quote not mine! (woops)
For some reason Its super hard to find 3/4 axles or even 3/4 ton parts trucks around here.. A guy up near Toronto had a D60 and 14ff from a 76 'burb but they were for full time
4x4... I'm keepin my eyes open..
