Steering column rebuild 67 barracuda
Well, this is a pickle. It is super annoying, when you are hunting for some seemingly simple part, that can derail your progress.
The bearing I used on my 70 Duster is the 2" OD, 1"ID. I'm guessing it's the ER 16 that you made reference to, which won't work for you.
Have you tried GOOGLE for a 2.25" OD, 1" ID, snap ring bearing?
Is there a Fastenal near you?
