Just curious if MOMO changed their screw size. I have a new MOMO and it has the same screw size as the old Porsche Design MOMO steering wheel. The PD, however has a recessed mount that's smaller than the extension which doesn't affect the flat faced new MOMO wheel.
To use it with this wheel, I'd need to have it turned down to the ID of the PD wheel and then drill larger holes and countersinks for the larger screws...
