Yes, the 70 Chevelle bearings. I have a note to use NAPA #46409 inner seal. Don't know if that's the same as a Chevelle inner seal or not????

Somewhere in the back of my mind, I remember the instructions in CCI's catalog that said to use a wheel bearing seal for a full size mid-sixties Chevy....Why I don't know.....Anyone else remember this?

The inner seal to use those rotors should be for 62-67 Full Size Chevy. I had to look the info up myself today. Info from Eckler's 2009 catalog in a installation how to

A National seal Part # 7934S for a 65 Bel Air has an outside diameter of 2.405 which is the same as the outside of a 70 Chevelle seal and an inside diameter of 1.875 which is the same the inside diameter of a tri-5 seal.
Just as I remembered......They were kinda' pricey at $10 each......Most of the other seals run 2-3 bucks a piece....Makes you wonder, Why!

I've just replaced mine and used the 7934S seals. Think they fit 63-68 Vette as well. When I asked for the full size Chevy seals it seems there were two different sizes used in those years.

How much were the seals?

I'm in the UK so they cost me £30.00 for the pair from a supplier over here....that's about $45.00. When I checked on the internet many US suppliers seemed to be about $20.00 a pair.
We pay a lot extra for shipping, import duty and sales tax.

The first set of seals I had sent were for an Impala and turned out to be wrong which is when I learnt there were two sizes used. As said previously the wrong ones were cheaper!
