I was commenting on my 1966 Catalina that I put an Addco 857 bar that is also 1 1/8”. That made a big difference even without adding a rear bar although I’m sure that would be better.
I did see the 199 bar described as 7/8” in a few ads but unless they’ve changed it, that’s incorrect. Mine is 1 1/8” and fits very tight.

Hope that helps you!

That is great information. I can see a 1 1/8" bar being a huge improvement over a 13/16" bar or 7/8" bar. Absolutely. If it fit a 63 it should fit a 62. These parts seem to all be listed to fit 61-64. As for the rear, I can see possible binding with the lower arm mounted bar. But why would it bind on car and work fine on so many other models? Possibly the greater travel on the rear suspension of the 61-64 cars?
