    Just for what its worth, all of the GPR drive shafts are the same except for the 02.

    I do not know the diameter though.

    Good to know. Thanks.

    Another thing, does anyone know the difference in hub size between the pre and post 05 pumps?

    GPR driveshaft diameter is .778". 00-04 hub size measures 2.403" from the tail. Do not have 05 and up pump out but the rear of a DF for that pump measures 3.065" . Can't find my thread gauges so your SOL on that. Maybe Solas has that info.

    What are you up to Mike?
