Alternative for power brakes
The master cylinder for the Omni, Daytona, Aires etc... from 83-88 has a 0.827 bore and is very cheap... $28-$36 at places like Summit and Oreilly's. Dorman #M39451 Cardone number is 10-1945 and about $20 at Advance.... less reservoir. Looks like you could turn the reservoir around.
Only issue is both ports are 3/8-24.
