Thanks Weeds, I don't need any measurements, I was only trying to help sort out the column question.

On my hot rod '54 I'm using '78 Monte Carlo clip and column, and expect to put it together without too much trouble.

1955 1st GMC Suburban | 1954 GMC 250 trailer puller project | 1954 GMC 250 Hydra-Matic | 1954 Chevy 3100 . 1947 Chevy COE | and more...
It's true. I really don't do anything but browse the Internet looking for trouble...
