    Have a 73 muncie and want to get new slip yoke.
    How long of a barrel is good to use for a forged moly 1350, 32 spline yoke ?

    center of cup to end of barrel can be 5.5" or 5.75 or 6.940 all kinds of them, need to know what would be best for trany at the track.
    seems like the 5.5 would be only in the trany about 3" or so with 1" play. just not sure that is enough..... Thanx

    They seem to measure them from center of cup to end of barrel.

    That would only leave about 2.75" on the output shaft :Do No:
