Cj5 Power brakes conversion

Hello, I have recently came into a 1979 Cj5 in really good shape and i was going to convert the breaks to power breaks. I was reading about some different systems and i was wanting to have a vacuum assist so the brakes will work even if the jeep stalls. However im not sure how to do this slash would like to know if anyone has any advice on the situation. Right now i have this M/C and brake booster: Tuff Stuff Performance 2131NB

It's brakes, manual brakes have easier stopping (the same pedal pressure) when the engine isn't running. All power brake systems use engine vaccume. With the exception of diesels. If the engine stalls, there is no vaccume. And that requires more pressure on the pedal.

If you're worried about having power brakes when stalled, maybe a vac canister? Mine doesn't aid as it stalls out. Neither does my truck, or wife's car. BTW, I snagged a booster off of an old s-10.
