Brewer’s Performance has served the Mopar hobby since 1981, specializing in A833 four-speed transmissions and the driveline components needed to rebuild or convert classic Chrysler muscle cars. The business grew from salvaging hard-to-find Mopar parts into reproducing clutch torque shafts and floor tunnels, rebuilding transmissions and Hurst shifters, and supporting racers, restorers and hobbyists with detailed technical guidance. Its VIN-matching program for lost and found A833 transmissions is an especially distinctive effort to reunite original components with their cars.
