    74 C10 front left disc locked

    I had this happen to me on my 76 C20. RH caliper would stick on, I could release it to get me home by cracking the break bleeder on the caliper. Replaced the flex hose to the RH caliper and all was good.

    AN fittings need to be drilled?

    Hi Bryans If you want AN fitting go to Aircraft Spruce. Real Aviation fittings that dont break the bank, I found them cheaper that most well known automotive shops. But the fittings tend to be blue. https://www.aircraftspruce.com/categories/aircraft_parts/ap/menus/ha/an.html

    Cracked frame/shock mounts help

    I have this kit on my C20. Works good. Where the cracks on the frame are, drill 1/8" holes at each end on the crack (stops the crack spreading further) then weld up the crack grind it back, paint, and use the offroad design kit. This is good for the rear end. The cracks are caused by the...

    Tires Plus says my Dually tires are too heavy to balance.

    Worst case. Static balance them yourself. Put an old spindle in a well mounted vice. Mount the wheel and let gravity do its thing. Tape on fishing weights on the inside the wheel rim at the top until the wheel wont spin on its own to another location. Mark where the weights are, take them off...
