I need to find longer bleeder screws for my 70 half ton, The new wheel cylinders bleeders are too short and dont clear the spindle, so I cant get a wrench on it. The originals I have are so stripped that I cant get them out. Does anyone know who sells them or at least what dianeter and thread size they are? I have tried Napa, Advanced and auto zone and mienieki without luck. if I have the thread and diameter size maybe I can match them up.

Thanks,
Mac
