My 1973 Duster has power disc brakes with 10 inch rear drums. I've got all the parts to replace the brake system, but the vacuum booster has been tough. Advance and Autozone can't get it, Summit and Year One don't seem to have it, or at least, based on the description of what they do have, I'm not sure one will be an exact replacement for mine.

I don't care about factory appearance or correct colors, I just felt that I should replace the 51 year old booster while I'm doing the rest of the brake system.

Anyone know where to find what I need?

Here's a photo of what is in it now. This photo is before I took the excess add on junk out and the insulation off the AC lines.

What is this booster, a Bendix series 1 or 2 or something else? I'll call that Lynwood place tomorrow.
 
That power brake booster exchange place wants $350-$400 to rebuild it. I know good brakes are important, but........

Maybe I can rebuild it myself, how hard can it be?

Are there any brand identifying marks on the booster anywhere?
 
DoctorDiff sells one if you’re not worried about matching the appearance

Bendix Style Dual Diaphragm Booster for Mopars

That said, is the booster working? Because I wouldn’t tear it down and rebuild it if it’s still working.

And of course there’s always just going manual brakes. I had power brakes in my ‘74 Duster and was very happy to replace them with a manual 15/16” master cylinder.
