Re: Disc brakes from a 87 burb

Your question is a bit confusing so let me see if I can break this down-

Donor- 1987 Suburban 4x4
Recipient- 69 C10 2wd
Front brakes- You want to adapt the disc brake system to your drum brakes. Since your trying to swap 4wd to 2wd I don't see this as being a fit. You might be able to use some of the components, but not all.

Rear end-(6 lug) It can be done, but unless you have a leaf spring rear you are going to need to swap all the mounting brackets. They are welded on, so it will require some fabrication skills.

Transmission- You don't say what motor you currently have, but the 700r4 will bolt to any small block. I am not sure what is required to adapt the newer style tranny xmember.

Would it be better to put the engine(tbi) and tranny(700r4) from the burban into the 69 or just the tranny? That depends on the condition of the motor and tranny. Id the TBI motor is low mileage, it's worth the swap. If you don't want the TBI then you can buy a carb intake for it as well.


I want drop spindles- Your best bet is to buy a disc brake conversion from one of the many forum vendors. I "think" they offer a 6 lug conversion with drop spindles. You will need to verify that to be sure.
