I'm away from the car just now and trying to get an adaptor made up to accept my QR spigot.

I have a Sierra steering column.

Can someone measure the OD of the steering column (steering wheel end), the round part where it exits the bearing before it turns into a hex. I have an OD of 7/8" in my head but want to be sure before I get the part made.

Thanks

Just measured with a micrometer 19mm or 3/4''

Cheers

That might make life a little simpler as my spigot is 20mm
