1967 904 Transmission spline

In a follow up, I'm gonna double check the numbers on my transmission to verify that it actually is the original transmission. If it is, are there any manufacturers that make a performance converter for the 18 spline?
I myself didn’t check on Hampton. I did t know about them. Everyone I ever got in touch with said they couldn’t help me with the low spline coin converter. “NEW parts” seemed to be the issue for them.

I ended up have the OEM converter restalled at ProTorque. Being the odd spline count, I could t find anything anywhere. After a long time searching, I called up ProTorque. At the time, they were right down the block from where I lived. Could have road my bicycle there.

The owner himself took the converter and hooked me up. Once I told him everything about the car and engine, he knew what to do. Tell who ever you go with, everything about the car and your intentions with the car.

These guys will do what ever you need them to do for your converter for your car and your intentions.
