Converting from 2WD to 4WD

[jacobs]

I installed my old 73 Blazer 4x4 drivetrain into my 70 C/10 w/rear coil springs about 12 years ago. The conversion wasn’t difficult. I had to weld the spring hangers on and do some cutting on my front crossmember because I didn’t relocate the engine rearward like the factory did. I even used the 73 front springs which are longer than the 67-72 factory 4x4 springs. The Blazer rear leaf spring hangers even worked out good even though the 4x4 frame is radically different in the rear. The only problem I’ve had with the conversion is braking isn’t as good now (due to discs on the front) but that wouldn’t be difficult to correct if I wanted to. It was senseless that GM used a different frame on the 4x4's IMO.
