I'm having a hard time cross referencing the rotor numbers and caliper numbers.
My truck is an 85 C10 that was originally a 6.2 with hydro-boost, the brake RPO code is J55 (heavy duty brakes), 5600 GVWR, 2WD.
The rotor casting number is either 3963996 or 3863886
I only looked at the right caliper and it's 18007153.
The calipers are big bore, I tried to measure the piston with a tape measure and it was around 2 15/16".
Any help cross referencing so I can buy the correct parts would be helpful.
