What adaptor do I need to fit an ididit column?

The top of the column is the same as the 69' or newer GM passenger car column (pre-air bag).  This is also the most popular adaptor used in the aftermarket industry.

All ididit inc. adaptors will match this spline. 

ididit inc offers custom machining to adapt most pre-69' original wheels to the top of an ididit column.  Call us for more details.
