AR Engineering offers two master cylinder adapters in order to match the most common configurations. These adapters are designed to mate the later model aluminum master cylinder which started to appear in the 1978 model year and was gradually phased into production. There are at least 3 different bore diameters used in RWD vehicles with the 1 1/32 diameter being the most popular. The light trucks used the same design but with a 1 1/8 diameter bore. Mopar Performance also sells complete aluminum master cylinders in two different bore sizes. We are partial to the unit used in the 1985 5th Avenue cars, but most any RWD master cylinder should work. Stay away from the master cylinders used on FWD vehicles. They look the same as the RWD master cylinders but many were designed for diagonal braking systems and may be calibrated wrong for your musclecar.
