1978 differentials
Hey does anyone know if the front and rear differentials from a 1978 1/2 ton 4x4 will fit under a 69-72 Blazer?

Re: 1978 differentials
The front diff should bolt right in but the rear end will not the spring pads on a 78 diff will have to be cut off and a new set welded on as the widths are different.I am planning on putting newer model running gear under my 71 also.

Re: 1978 differentials
the center bolt holes on the 73 up fronts are about 1/8" off on both sides, I just forced the springs outboardwith a pry bar
