Will the front axel from a 1/2 ton 79 Suburban fit a 72 Blazer easily? Should I just have the original axel rebuilt? How much would this cost? I am looking to buy the Blazer and the guy said the front carrier is cracked and it needs head work. I have a 79 Burb for a donor vehicle if needed. The Burb is my daily driver right now but plan on getting rid of it anyways and am trying to find any reason I can to get the Blazer. If the axel can swap I should be good to go cause I have a good engine to put in it. Also, do they make a/c compressor brackets for now accessory hole heads? And how do you do that np205/203 doubler thing? Thanks.
