This 2 piece billet aluminum adapter will let you adapt a 5 hole Steering Wheel with a GRANT 72mm bolt pattern to any MOMO, OMP, Sparco, Forever Sharp or NRG steering hub adapter with a 6 hole 70mm bolt pattern circle.
The lower flange is bolted to the steering hub adapter using the 6 M5x16 included flat head bolt. The upper flange is then mounted to the lower flange using the 4 #10-32 x 3/4″ flat head bolt. Finally the steering wheel is secured to the adapter using the 5 supplied #10-32 x 1/2″ flat head bolt.
Please make sure you are using a 72mm 5 hole pattern steering wheel on a 70mm 6 hole steering hub adapter. This adapter won’t work with 74mm hole pattern or any other combination. I needed this combination on my car to adapt an MPI 5 hole steering wheel to a MOMO steering hub adapter and couldn’t find anything online. Contact me before buying if you want to make sure this will fit your application.
These adapter are CNC machined out of 6061-T6 aluminum and finished with a shiny black anodizing. The final thickness is 20mm (.787″). They are installed between the steering hub adapter and your steering wheel.
