Chevy Small Blocks 283, 305, 327,350 into Jeep YJ Wrangler- Crossmember & Mount Kit
Trans-Dapt Performance started offering transmission adapters and engine swap motor mounts back in 1959. Our motor mounts make mounting your transplanted engine to the chassis easier, and more secure.
The stock motor mounts must be completely removed from the frame before the Trans Dapt Crossmember can
be installed. It is also recommended to remove the front shocks for ease of installation. Modifications to the
skid plate (re-drilling) is required for all applications.
Trans Dapt has engineered this Crossmember mount to position the engine in the best possible location for
serviceability. Driveshaft modification may be required for some applications. TD has included 2 5/8” spacers
to allow lateral adjustment. By using these spacers you can adjust the motor mount pads 5/8” to the front or
rear of the Crossmember. This will allow you 1 ¼” of overall adjustment from front to rear. The 7/16 flat
washers must be used on both sides of the bolt that slides through the mount pad. We have also a longer set
of 7/16” bolts for use with the spacers.
Mount the Crossmember using the factory motor mount holes on the shock towers. Install the Crossmember so
the mount perches are aiming to the rear of the vehicle. The lower bolt comes through the outside of the shock
tower and threads directly into the threaded end of the Crossmember. The upper bolt and washer is to be
installed from the inside out with a nut and washer inside the shock tower. We highly recommend the use of
thread locker on all nuts and bolts.
