I bought a used steering wheel recently. It came with a Racetech quick release coupling bolted to it.
I had originally planned to swap over my own QR coupling from my old wheel, but, turns out, it will not work with the wheel I bought.
So, I'm hoping (long shot) someone might have a splined slug like the one pictured below on the right.
It is described as:
The hardened steel splined slug has to be welded to the steering column. The diameter of the splined section of the slug is 19.00mm and has 15 splines plus a master spline.
Thank you.
