Rear disc brake???? blackbird, wilwood, brackets - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Question.... Who knows if the blackbird kit for "71-87 5-lug" will work with the wilwood D52 calipers and the stock rotors from the front wheels.

I see where Captainfab has made a bracket for the D52s but it says, "These brackets will bolt onto the truck 12 bolt rear differentials from '64-'82 and the 10 bolt truck differentials from '83-'87."

So what brakets out there work with the 12 bolt 5 lug for an 83-87 with the D52 calipers or Wilwood D52 calipers? It doesnt really matter to me what kinda rotors they are.

Can some of you guys post up what your rear disc conversion combo consists of.

Thanks a bunch

I didn't think any of the 1/2ton 2wd trucks had 12-bolts in the 83-87 model year.
I thought they were all 10-bolts by then.

I believe that's correct. 12-bolts through 80-81; 10-bolts after.

Yep. No 12 bolts after '81. I don't think any rear disc brake kit will work with a front rotor from our trucks. The design of the rotor is completely different; they are made to ride on a spindle, vs sitting on an axle flange.

Ok thanks guys,

after I posted this someone did tell me about the 12 bolt not going past 81'. But thanks for the replies and information.
