I have a MOMO wheel in my 67. The adapter was the difficult part to find ( about 8 yrs ago ). Its 1 inch tall billet aluminum between the column shaft and the wheel. I took the shaft diameter and spline count, and the height desired to some website/vendors catalog/chart. I filed away a master spline also. Anyway... there isn't a Grant part in my assembly. Just the 1 adapter. Good luck with yours.
