Can some tell me if the front Bendex rotors/ calipers from the '77 1-Ton. bolt inplace of the Delco front brakes on my '77 3/4 ton? Are the wheel bearing #'s the same? Thanks.
Dan

in your 1 ton you should have a dana 60 and in your 3/4 ton you should have a dana 44 none of the brake parts are the same and nether are the bearings

I forgot to mention this is a 2-wheel drive with a 14ff rear.

I have no idea, just search autozone or checker websites and compare part numbers.....

Thanks, From what I can find after checking P/N's it will work.
Thanks again

Hmmmm, you might want to double check that. I had both the 3/4 and 1 tons (latter years than 77) and I know for sure the calipers are different. I'm not sure about the rotors, spindles or berings.

I did the 1-ton (Bendix) brake upgrade on my 3/4-ton 2wd Burb. I had to swap the caliper, knuckle, rotor, and lower balljoint to make it work. The caliper mounts differently, rotor is thicker, and the bearings and balljoint are larger.

FWIW, not all the 70's 1-tons used Bendix brakes (rpo JB8)... some used the same brakes as the heavier 3/4-tons (rpo JB7).
