Hi folks, merry Christmasto you all santa2

Please could someone kindly confirm the number of splines on a three wheeler steering column?

I'm researching a quick release steering wheel setup for my 2012 Duratec Plus 4, and I'm rather taken with the one handed operation of the three wheeler cental push release version.

If I can find one, and it fits my Plus 4 column, it would be exactly what I'm after drive

Thanks in advance, Dave.
