Brake Conversion please confirm the plan

[lsteiner72]

Hey guys,

So the truck is a 70 C-10 long box and what I'm looking to do is lower it and convert to front disc and 5 lug all the way around and what I'm looking for is a confirmation on the parts needed for the disc/lug part.

I bought lowering spindles from CPP for the 70 (for original style ball joint) and have welded slugs in the axle holes to re drill.

The plan is to get 5 bolt rotors from the parts store for a 72 along with 5 lug rear drums for a 72. IS THIS CORRECT? Will the 72 rotors fit the spindle? Along with the 72 5 lug drums being good to go with the 70 drum brakes? Will stock 72 calipers fit the CPP spindles?

I plan on then getting the proportional valve from a 72 along with brake master and booster.

Also is a 5" bolt circle the way to go?

Thanks guys for any help.
Regards
Lucas

I would check out this FAQ if you haven't already. It has a lot of info for this swap.

You should probably check with CPP about the spindle. You may need to change your ball joints and tie rod arms.

Also, to convert to 5 lugs in the rear you will need to convert the axles to 5 lug. A few ways to accomplish this are getting a complete donor rear end from 71-72, aftermarket 5 lug conversion axles or redrilling your axles for 5 lug
