Oem Gts Kelsey Hayes 4 Piston Calipers

I bought a complete set of 4 piston brakes; calipers, rotors (shot), spindles, hubs, etc. from a member here on the forum about a year ago for $75 IIRC plus shipping. They were off of a newer car but I think all of the sbp stuff is the same. Everything I bought needs to be reworked, ie the calipers need rebuilt etc. I thought the price I paid was more than fair. If all of the parts you have are useable as is I think I've seen them go for somewhere in the neighborhood of $300+. Maybe more. I think some places charge over $100 core charge each for the calipers, but I just checked Autozone & they're charging $25 to $30 core charge.
