Another brake swap question, hopefully a pretty simple one though

[Adam4pt6]

So 1st off, thanks for dealing with my **** ton of questions.

I have a 69 c20, and I'm looking to swap to power discs in the front and lower it.

Right now I have: stock 1969 c20. And I have rotors, calipers,and tierods (in, out and coupler) from a 1982 8 lug suburban.

In ordeer to make it all work I would need (drop)spindles for the 82 suburban, upper and lower ball joints for the suburban (I can reuse my a arms correct?). And a booster, master cylinder and proportioning valve off of a 71/72 c10.

Is all of that correct? I'm about to order the rest of the parts and just want to be sure before buying all of it.

Thanks again
