Dont you have any garages around where you live. Look for the old guy (like me) who has been doing this crap for 30 years ( I am 52).
Cadillac also had tilt telescope columns, in more than one year IIRC.
My 65 Coupe De Ville had one, and I remember working on a few in 70s models too.
Just sayin...maybe some of the parts will directly interchange.
I repair anything on a car, an old steering column is a piece of cake(for me)
just need to find a decent garage close by to take it to.
Maybe someone else will chime in who knows a good place close by to you or at least some where to send it.
Fact is stranger than Fiction
