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
