Bendix brake booster.

I'm in need of a current source for a Bendix booster for a 1969 Chrysler w/disc. Parts book says all C body, including Imperial. (2883091).
I got a booster and cylinder off a 1 ton motorhome but the mount bolt pattern is different. $350.00 for a repop is a last choice.

Does anyone here have a known good used one.....? Or know what years will crossover.

Will.
