Steering column interchange

[Mohawk Freak]

If anyone knows for certain the answer to this I'd appreciate it. The steering column in my 73 is non tilt. This won't do of course. I have a 70 tilt/tele and a 74 Pontiac Gran Ville tilt. The 73 is a different chassis obviously. I know the Pontiac unit would go into a Chevy/Buick/Olds, but Caddys are often their own animal.
I'll take them all apart and mix/match if need be, but I'd like it if one would be a direct bolt in. The length of the column and position of the under dash horseshoe would seem like the likely differences. Anybody done this swap by chance?

I think cadi's have there own. I did a tilt swap into my 72 when I found the right 72 column. Might be able to used the cadi lower with the GM upper and make it work but dont know without looking at them

Thanks for the insight. I'll make a Frankenstein out of a couple if need be. Looking for the one that just bolts in would be too easy!
