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. The Standard 3-bolt Adaptors are 1-1/8″ deep. The Standard 5, 6 and 9-bolt adaptors are 2-1/2″ deep. We do carry an adaptor for the Stock GM 1955-68 Wheels.
