Where can i get a steering wheel boss for a 93 cav sri 16v SFi engine, with an airbag! i`ve already bought a raid boss 78X which according to the listings wil fit, but it`s missing a large hole for the wiring to go through and the spine that cancels the indicators accoridng to the guy that tried to fit it, he reckons it`s the boss for a non airbag model. The steering wheel is a momo course, don`t know if that makes any difference.
