RBT spline size

[DaveM]

I have a standard 5 speed RBT. What is the spline diameter? Ordered a replacement clutch disc 1 1/16" 10 spline for a Ford Mustang (10.5" plate). It won't fit the RBT splines. What size clutch disc should I be ordering?

In my notes from RBT it's the Chevy size, 1.125 26 splines
hope this helps

I measure 1.125" 10 spline, but I'm confused by Pantera ZF references to 1 1/16" 10 spline. Any other explanations?

 

The RBT uses the BMW M1 spline. It is 29 mm x 10.
Mcleod has the correct hubs.
Part number for the disc only 272180R.
The R is for a offset hub, which moves the hub closer to the box for better spline engagement.
The pilot bearing on the M1 shaft is 12 mm, so either make a bronze unit, or we make a roller bearing set up.

The Pantera ZF uses the normal 10 spline Ford, and the standard pilot bearing size.

Hope this helps.

Thank you Dennis, especially for the McLeod #!
