I ordered a new one from Rock auto for drum drum 10" and it came big small reservoirs as well ?? what gives The 1970 listing for 10 drum was drum is adifferent number but picture shows both the same size, check out Part number 3461184on Google seems both manual and power master cylinder we used on 71 car with drum brakes first year for bale as well as the larger 1 1/32 bore ??
