69 c10 brake question

[medwards]

Newbie to forum. Met a guy at swap meet this past weekend who told us about site and joined immediately. Great Site.

Have been reading threads and have a question I am looking for confirmation.

Have 69 c10 2 wd p/u (father son project) and we are definite on disc brakes. I have a set of 72 suburban spindles, calipers, a arms(upper and lower) and linkage. He wants to keep 6 lugs so I am searching for rotors. If I understand correctly, ECE or CPP rotors are six lug but will they fit stock spindles? Will stock calipers fit these rotors? Also, 68 master and booster should work as well (disc/drum)?

Any pitfalls or tips advice that we may have missed reading forums.

I know this may be redundant but would appreciate the guidance.

Thanks for your patience.
