I found these, Harvey…
Any good?
Quite a few more on eBay so plenty of options. Maybe find a supplier near you to actually try one, if they cannot say if it will definitely fit?
You’ll need a (Momo?) steering wheel too.
One other idea…
I note the standard wheel nut is held on with a tabbed washer. How about remomving it and fitting a robust stainless steel ‘R’ clip instead, via a small drilled hole in the appropriate spot?
