They were extremely rare unfortunately. You are looking for a booster that only existed in 1993-1994.
Not sure if you know but the 1995 4.0 booster was also one of a kind. There were tons of 95 4.0s sold yet really very few of those boosters available. I’m afraid the one you’re looking for is even harder to get than the 95 version. Technically you could swap to something else if you bypassed the ABS and got different lines and MC. Hard to say what your best option is really.
