Complete rebuilt engine, L Head, 134 Engine. We believe this is a Willys MB block due to the location of the serial number on the oval pad on the upper passenger side corner of the engine block. This also has the early chain driven camshaft and timing chain. Note: This engine has a very small leak at the rear main seal due to a pitted rear crankshaft. We are selling this engine at a loss due to this small leak. We have over $4,000 in this rebuild.

Wagon wiper motor conversion

The unit bolted right on and lined up with the cable assembly side prefect and has just the right amount of windshield sweep. When the motor is turned off , the blades continue to the bottom of the windshield before motion stops. The motor , switch and wiring are top quality. .

Disk breaks in a Willy’s!!!!

These are amazing!!! I have owned a few Jeeps but have never had one that disk breaks, the calipers are great and the rotors are heavy duty, if your in a Willy’s you need these!
