Steering Boss splines

[Waitey]

Gents,

Does any know who many splines and what size is the fitting on the top of the steering column.

I'm looking to get a replacement steering boss.

Car is BDR 153.

I do know that it's not an off the shelf item (Grant, Sparco, etc...) and the design has changed over the years so buying a current production RT4 hub may not fit your RT2 steering shaft.

I'd contact Quentin Z as he had a replacement made.

Thank you spdbrake.

I've just finished your steering column upgrade too over here in the UK, which is a bit more involved getting parts (and import duty!!) etc, but so far its working really well. So thank you for that too!
