Changed Transmission need a slip yoke

[Jimmy S.]

If it isn't one thing it is another. Replaced my old engine with a rebuilt engine. Replaced 3 speed saginaw with a new process MY6 trans.

Now I need a 27 spline silp yoke.I should be able to use a 26 spline with wide groove. I need a replacement slip yoke that uses the same U joint that
1966 C10 drive shaft uses.

I have another saginaw,date code s2s22,it has the 26 spline with the wide groove.Trans. is from a 1966 Chevy C10 truck.If I could date this trans.
Could I order a slip yoke from that year trans?

Thanks,Jimmy
