    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!

    CJ 5 alternator conversion

    All the brackets were well-made and fit perfectly. The belt was too short, but after talking to their customer service department, I found that I had an oversized water pump pulley.. all in all a great improvement to my CJ

    Alternator install

    It worked great. The provided bracket lined up perfectly and the alternator and provided longer belt finished the install. It worked as advertised.

    Alternator Conversion Kit, 12 Volt, 4-134, 59 CJ5

    The kit is well constructed and works great with exceptions.
    [1] The belt tension bracket interferes with the oil filter line at the timing gear cover. I had to replace the oil filter hose with a steel brake line that would allow a 90-degree bend close to the fitting.
    [2] Because of the bracket being made straight it hit the top of the alternator preventing proper belt tension. Again, I had to modify the bracket by incorporating my old, curved generator bracket with the new one.
    [3] THE SOLUTION: Eliminate the weld on spacer. Manufacture a new bracket with a double offset bend and a curve to allow proper belt tension.
    NOTE: I would use a thin metal prototype to assure proper function before manufacturing the NEW bracket from a heavier stock. Except for the useless bracket provided, the kit is definitely a FIVE STAR.
    PS: Might want to include a ROADMASTER 690 Single Park Light Diode.
