BJ8 brake booster

Power Brake Exchange in San Jose, CA is usually recommended. We had the booster for my dad's '46 Chevy 2-ton rebuilt, and have no complaints (except maybe the cost, which is usually around $250). They're about 5 miles from my house (a bit farther for you). I've been to their shop; it's grimy as heck--not surprising with brake fluid everywhere--but they're standup guys and the tech I talked to was conscientious and very proud of his work. He had several Girling boosters on his bench. Apple Hydraulics may do this, but I'm not sure.
This job is doable by the home mechanic who's willing to learn the principle of operation. It's 2 brake cylinders--a slave and another master--in one unit and, like most brake jobs, you may need to get one or both sleeved. The jury's still out on honing aluminum; some say never some say it can be done (I'm not comfortable with the idea). There's a leather seal on the vacuum cylinder that's backed-up by a rubber seal; it's imperative to get the seal cut to the proper length. This is the most complete kit I've seen:

You might also give them buggers over at White Post in White Post Virginia a call.

I actually did so in depth research about the Rebuilders and one customer posted a picture online from the Rebuilder they used and at the bottom of the box was an Invoice from Power Brake Exchange for half the amount of what he paid the Rebuider he used. I believe PBE does most of the rebuilding.

The guys at PBE told me as much (they do rebuilds for WP and, IIRC, WP may do some for them if it's a really esoteric build).

I had a problem with mine the first time it was rebuilt but PBE rebuilt it again at no charge. I might add that there was considerable time between the original rebuild and the latest rebuild.

I would stay away from PBE. It is true that they do WPs rebuilds, among others. I had an expensive issue with them when they lost a 190 SL cylinder and refused to replace. That one cost me and I will not use them again. Have switched to Karps, as they do all work in house as well.
