UMI Performance LSX motor mount hardware kit for 1982–1992 applications includes Grade 10.9 bolts and ny‑lock nuts to mount an LS engine to an aftermarket K‑member or aftermarket LS motor mounts. The kit is intended for aftermarket K‑members and adapter mounts; it will not work on factory F‑Body K‑members due to bolt length differences, so verify fitment before installation.
