I didn't have one of my tuff wheels handy so I used a '72 e-body wheel for comparison but it is the same depth as the tuff wheel and non-tilt rimblow wheels that use the adpater can. The rimblow wheel here is a '71 for tilt.

I question the adapter above because it has the parts for the horn contact and turn signal cancellor which would be different on the tilt. I'd have to get my tilt column out of the garage during the day verify that.
