No ones else has these! these are way better than those rickety clips that cut the boots of the caliper pistons. must have for any mustang gt style caliper. Miss labeled that one does one caliper. ONE = one kit for BOTH sides. description is misleading. needed for 2 vehicles and bought one for each side (as it says i need 2 per vehicle), now i have 4 kits for 4 vehicles. not upset, as i will use them in the future.
