Chevy engine conversion just got a little easier for YJ wranglers. Advanced Adapters saddle mount requires no welding, only the stock engine mounts need to be removed from the frame and the rest is bolt on from there. Includes saddle mount, 2 rubber isolator mounts, and required hardware. Note: Will not work with LT1, LT4, or LS1 engines or 1997-newer TJ Wranglers. For stock oil pans only. Rquires electric fuel pump.
