79 brake booster options?

Need a brake booster for my SA, nothing new I can find so far. Seems there oughta be something from other cars that would work.
Anyone had success?

you can have yours rebuilt, which is inexpensive. swapping boosters is easy, every car newer than 1977-ish has the same bolt pattern on the firewall, but you would need to use a different master cylinder, and then that probably means changing brake lines and stuff

like the SA, my RX3/4 came with small brake boosters. ive upgraded them using 81-85 booster but i had to relocate the clutch master cylinder to make room for FB booster. in addition, i switched to FB pedals but tweaked them to clear the wheel well. im currently working on my SA and will be upgrading to FB as well. if youre interested, the SA booster will be available. Send your # to me via PM so we can discuss it further

The issue with my current one is it’s so big it overlaps the spot where the clutch slave will mount (auto-manual conversion in process) so rebuild isn’t an option.
Maybe this is an FB booster installed by PO?
