as long as you have an aftermarket boss and wheel you can buy a fitting to go between them
the thinnest is about 20mm

I could be wrong but I have the feeling that it is a Triumph size boss you need - Spitfire etc

As far as I can ascertain, it is early Spitfire (not mark V), TR4, Elan etc... I think this is the right one but I haven't tried yet: https://www.ebay.co.uk/itm/LOTUS-ELAN-E ... 2891945431

I have a Mountney boss for an early Spitfire that I bought in error if you’re interested.

Great information many thanks from all above,I just need to decide which wheel and boss to go for then, I'm assuming the cover behind the wheel but not the stalks will need some modification,would I be right ? Going for a flat wheel not dished ,frodo monkey thanks for the offer may well bet back to you on that .

Looking at the pictures of Momo wheels(?) fitted to Sabres, it looks like the boss is just attached in front of the steering cowl (the plastic part which the stalks exit from). One would think this would make the steering wheel too close, but people don't seem to have a problem...

If you can tell, it appears the boss is added to the column

I think that the Momo (Corsa type D35) wheel itself is very thin and the boss is about the same thickness as the standard wheel?

Many thanks for the photo, I suppose when you subtract the depth of the original wheel the difference isn't going to be that much .
