You'll need to get a used one. I dug around once, the booster is unique to the FD.
They should be fairly common used. They pretty much never go out so they really aren't in demand.

It's like 2 bolts and a hole. May need to drill some holes , but there should be something that fits with a little modification. The Mazda 929 master cylinder bolts up to an FD booster. Maybe the booster itself is pretty close and can be modified to bolt to the fire wall.

The LHD and RHD boosters are different, the nipple for the vacuum line is in a different spot.
To OP, deleting the booster is a whole thing, it gets pretty advanced and unless you are VERY comfortable with braking systems I'd stick with a stock setup. This is NOT something you want to mess around with, failed brakes can lead to death of you or others on the road.
Keep it simple, keep it stock. It really shouldn't be hard to find a good used one for a very fair price.

The delete kit from Chase Bays already did the research to allow a similar pedal feel without the booster. It comes with a big Wilwood master cylinder (over an inch for the FD), reservoir, bent steel line, and proportioning valve, with an offered clutch line as well. You just tel em what chassis you're running and they send the MC according to if you have an FC, FD, Supra, Mr2, etc...
Downside is it comes with -3 fittings so you need an adapter to get it to ours. I coupled it with an ABS delete kit from Proline Motorsport, removed all the OEM lines and replaced with braided (with a few colors available) lines. Granted I can't comment on how it all feels yet as it's still not running, but it looks great.

the firewall to booster bolt pattern seems to be some kind of standard, every Mazda from 1977+ is the same as well as Subaru and even Ford.
that being said they then vary in diameter, depth, and of course the master to booster pattern is semi random too
Manual brakes scare the crap out of people, its pretty rare to drive a car with them.

Could be, I've never heard about it. Just searched around on the forum and didn't find anything to that end.
The LHD and RHD boosters are different, the nipple for the vacuum line is in a different spot.

I'd just get a US LHD booster. Look in the classifieds on the forum for people parting out cars, also there are a few guys that have tons of parts (Fritz Flynn, TomSN16) - message them and they probably have one on hand.
No sense getting a RHD part and having to cobble up something to make it work.
