    Driveshaft bolt length.?

    I am trying to order 16 x new driveshaft bolts for my 70 type 911 gearbox. The PET is showing two sizes as : M10 X 48 and M10 X 55
    What is the correct length to fit the shafts to this type 911 dogleg box.? The dealer is stumped.

    Thanks in advance

    They should be the M10 X 55. 70 911s used the thicker CV joints. Just be sure that your CVs are the ones that came from the car.
