I used CPP. Went together great and their tech was great help when needed. I bought a 4 wheel disc kit for my 70 Monte. I painted them orange. I think cost was around $1300.00 at the time for everything including slotted rotors. The calipers on front were used on 70’s trucks and rears were Lincoln continentals they told me. Only mistake i made and had to take back apart / reassemble, was not coating all the shims / bolts, etc in brake system grease. Also the brake shoes were crap and left black dust all over my rims, so i bought better shoes which eliminated that. All in all worked out great and have had zero issues. I know its a cheaper conversion kit, but i wasn’t going to spend 5k on a system.
