    Does anyone know if there is a difference in axle widths from 72 and before and 73 and later. May have a line on a 72 and hope to install my already geared axles from an 84 Blazer? Thanks in advance.

    Not sure about total width of the axle, but I seem to recall that the distance between the spring pads changed. You might need to do a bit of welding to relocate the spring pads.

    Since one of the pads is part of the diff housing up front, you can't move it. You might want to get out the measuring tape and compare the two front ends very carefully before committing the cash on the '72.

    The fronts are a bolt in. I am planning to install a 1979 Chevy Dana 60 front in in my 1960 GMC Suburban. It will be abolt in. The spring width is the same from '60 on up. The rears varied slightly, so make sure you measure them before purchasing.

    Here's a pic of my rig...1960 GMC Sub, Chevy 427 engine, SM465 trans, NP205 case, '72 3/4 ton axles with Detroit locker in rear. This is an older pic, before I installed the 4" lift and 35" BFGs on aluminum rims.

    Nice Ken! I love those 4 door trucks. Ultimate family hauler! I wouldn't want to buy tires/wheels for that though.

    Thanks for the info guys. I can get the 72 pretty cheap. I will most likely pick it up and see what swaps I can do or just gear the axles under it. Thanks again.

    OhMyGawd!!! [​IMG] The dually is a true beast! The Sub is gorgeous.

    A friend of mine has several pictures of the '63 Suburban that he rolled many years ago on a Colorado trail out near Monarch Pass. I'll have to borrow them and scan them in.
