    Anyone know where I can get a Cruise-O-Matic(Out of a '63 Thunderbird) slip yoke? I think it's a 31 spline. I've looked,but not sure where to get one.

    Okay,it might be a 30 spline. I'll have to recount the splines on the output shaft. Anyone know what aftermarket one's will fit if it's a 31 spline(I'm pretty sure it is)?
     
  4. I should have one. I usually save them to keep the dirt out of the trans.
    I'll check tomorrow.

    i'm pretty sure a c-6 ford yoke is the same this will make your search fairly easy.

    Okay,this might be a stupid question,but what's the difference between a 30 on 31 spline slip yoke,and one that just says 31 spline?

    31 spline yokes can be found in many Ford trucks from the 70s. A C6 has 31 splines and uses the same yoke. Some cruise-o-matics are 28 splines.
     
  13. I've got a couple of extra's I'll ship one Tuesday with the 3 belt waterpump pulley.

    Measured all of the critical dimensions. 31 spline, ID= 1-5/16 OD= 1-11/16

    Here's about what all the measurements should be:
    [​IMG]


    • Length to center of u-joint... Dimension #1 = 6 inches
    • Barrel Diameter... Dimension #2 = 1 11/16 inches
    • Barrel Length... Dimension #3 = 4 1/4 inches
    • U-joint cap diameter... Dimension #4 = 1 1/16 inches
    • U-joint width... Dimension #5 = 3 5/8 inches
    • Series... 1330
    • Spline count... 31
