My wife's daily driver is a 65 Fury. Today the power brake booster took a dump. It's a single reservoir. We plan on doing a disk brake swap at some point but I need to get it up and going sooner than later. I see there are several suppliers online, but I'm not sure who to trust. Any suggestions?

Well, I cant help with any info on aftermarket kits but I would look for a 4 door 67-68 c body for parts and grab the brake pedal assembly with all the hardware. then buy reman booster w/master from RockAuto.

You can buy it for drum or disk brake applications,

I've heard such mixed reviews about Roc Auto. There is a place here in town that might rebuild it. Gotta call in the AM.

My '65 Sport Fury had a Midland-Ross booster that I rebuilt myself. The procedure is in the FSM. But it would probably be easier to call Booster Dewey and have him do it. This was 30 years ago and you could still get all the parts through Chrysler.
