Why do you need to know? out of curiosity. Ive ripped off my steering wheel over a couple dozen times, It shouldnt be hard for me to find out.

 

I building a custom part for my wheel. I found it though: 14 X 1.50

 

oooooohhhhh, do tell.

 

I should say I'm having a custom part built. When the all the bugs are worked out I'll show and tell.
