A friend with a Speedex 750 told me the steering wheel boss on an Austin Healey 3000 has the same spines. He owns both cars, so I'm confident that they are interchangeable... if you get a Moto Lita boss you could fit a smaller wheel. Some of the bosses on Ebay have a deep tulip shape like the Ruby wheel so would give both benefits.
