When installing, if your shifter arm is not removable this product will not work. We sell/use IDIDIT steering columns, and they have removable shifter arms.
The Forever Sharp steering column billet aluminum mount works great to mount the steering column to our firewall panel. It’s looks great and allows you to get rid of the original bracket. The donut is 2” and fits the original column and the IDIDIT. All older GM steering columns are 2”.
