While doing an overhaul on the front end and getting ready to have the discs turned and take out the booster to send away for rebuilding, I came up with a few questions on stuff I probably need. The right front wheel bearings are probably the source of a rubbing noise, so I'd like to replace them on both sides. From what I have been able to learn, Timken's SET5 and SET3 would take care of the inner and outer, but what seals or anything else should I get and install? At Rock Auto's site, I only see a front inner seal offered - is there more than just that?
I'm still new at this classic car hobby, so do please forgive the hand-holding!:lol:

Separately, when taking off the master cylinder, I found that the bracket to the booster was cracked somehow and one of the little "ears" fell off. Are there replacements for that bracket, along with the gasket and what looks like a foam seal, available anywhere? Any other replacement seals and gaskets I need to pick up related to the booster and master cylinder?

The broken spacer plate and gasket can be found on plenty of power brake Chrysler products of your era. Only inner wheel seals for the front.
 
Unfortunately, my searching so far has only found two-bolt spacer and gasket sets for a Midland booster, not the four-bolt it needs. Classic looks like they had the right one at some point, but their site says it’s discontinued.

Strangely, the few photos I’ve seen of four-bolt spacers have an entirely different gasket. Did somebody do something weird to mine in its previous life?

You should try contacting some of the used Mopar Chrysler suppliers like National moparts, Murray Park, swap meets, wrecking yards, etc...
 
Do the 2-bolt models just have a "blank" where the hole would normally be? Same ID of the sealing part? IF the 2-bolt models just need the additional holes drilled, is there a handy drill press?

Seems like part of that "gasket" is also the "filter" to keep things out of the booster internals from the outside, ambient air of the engine compartment AND to allow air to equalize pressure in the booster as temperatures might change?

Might it be possible to clean, re-attach the broken ear, and re-use the existing part? I don't see that it is a "critical part" that really needs to be replaced.

Just some thoughts and suspicions,

You can find sheets of various gasket materials, which you can cut with scissors and an Xacto knife for that seal. That bracket likely will be best junkyard sourced. If it's ferrous, find a welder....
