Do they make a sparco and i believe its the same as momo 3 bolt to grant 3 bolt? My grant is a 3 bolt pattern as is my wheel. But grants 3 bolt pattern is not as big as sparcos on my wheel. So as of now unless they make an adapter or i drill and tap new holes it wont work.
Tomorow at work im going to heat up the splinned collar on the grant quick release and see if it fits on first. Ive counted, has same amount of splines as my column so not sure why it wont slide on. If i can get it on, im going to measure out my bolt pattern on my sparco wheel and then drill out the grant hub to match and tap some treads in. Should work if all goes well, just have to be pretty exact otherwise the steering wheel wont be mounted center
