Ive gotten some different responses when Ive asked this question previously so I thought Id ask here too. Can I bolt in the 3/4 ton axles out of a 1974 4x4 Suburban into a similar 1974 Blazer? This may seem like a dumb question to some but Id like to do it. I dont want to change spring perches or mounts on the axles but it appears (from looking at both) that I can. If it is a bolt-in what about the drive shaft? custom or the same as the original Blazers?

Have access to both of them? Grab a tape measure, thats going to be the easiest and most precise way to figure it out...

I think a tape measure is the best bet. one of the things to measure is were the center eye bolt is on each side of front and back axles. on this measure the front from center eye bolt of springs the the center of the other side and do the same for the back axle. then measure the same places on the donor truck. even if they dont measure up perfectly, you can cut the perches off with a torch. then go to local auto parts store and buy perches. grind the excess off of where your going to weld and ge a clean space too so there is good fusion. and then find absolute center on the axle and mark that point. then take the center eye bolt measurement and devide that by two and take the halfs and go from the absolute center and measure out and make a mark and put the center of the perches on that spot then mark the edges of the perches where they go and weld them in that spot. i have done axle swaps in a few trucks and none of them have matched up perfectly so your in for a little work but it is all easily done if your handy with a torch and welder or you have afreind that is.
