I just bought rear KYB AGX, and I am swapping them for my Tein Flex coilovers(blown). However, the KYB's did not come with mounts. I understand tht the OEM mounts (and all other hardware) will fit the KYB's. But, does anyone know if I could use the pillow-ball mounts and the rest of the hardware (ie: bumps, washers, bushings) from the Tein coilovers with the KYB's.
