Which coupler for DD to 36 spline 5/8 ? Can't find a fit!

[robcuda]

Hello,
I have a 64 Cuda with PS. Putting in a different column and need to go from DD to 36 spline 5/8.
I have tried Flaming River and Unisteer. Neither will slide over the 64 Cuda male spline!
Do you know of one that will work? Or am I doing something wrong?

Thanks in advance for any input!
Rob

5/8 seems very small. How sure are you of that?

I put a caliper on and it measures 5/8. I thought it might be 3/4 but it's not.

Here's what's available at summit, I brought up the 3/4 DD but other sizes/types are available...
Borgeson Universal Steering U-Joints - 5/8 in. 36-spline Shaft End 1 - 3/4 in. DD Shaft End 2

Thanks for the input. I may now try a Borgeson and call them first. Have you ever heard of 36 spline 5/8 not fitting from certain manufacturers on A Bodies?

The only cases I have heard of causing difficulty is sometimes a pair of splines is made as as an keyway for an index. Usually most splining problems are from burring or sometimes splines not fully cut, a little cleanup with a triangular file can help. It’s best to keep a pretty good interference fit on steering couplers, so be careful not to take too much material out when things have to be cleaned up or modified.

But no, I never got to work on an early a body, so my experience there is limited.
