Squats. Three sets of ten reps, every other day. Sorry, I had to say it.
A week ago I was in a scrapyard and saw an older 5 with the booster and master cylinder still on it. Not much help either. But if I get back there soon I'll look for part numbers for you.
I think that Jeep used Delco Moraine boosters, which were on all GM vehicles. You might start with a Holden dealer and see if a booster from a passenger car will bolt to the firewall. Once you have the booster it should be pretty easy to get the right master cylinder. Sorry I can't give you a particular model.
I might have been born at night, but it wasn't LAST night.
