How come all my manual drum cars have disc master cylinders?
Here are two other disc brake master cylinders that were installed on a manual drum car, plus the 300 had one also. The front MC is a 3699263 Mopar MC which is for a later car for sure. Has a 1 or 1-1/32 bore. That's the one that was being used on the '68 The rear MC was installed on my '73 manual drum 9 and 9 parts car, same specs, plus another that is on the 300.
1. Are the manual disc MC's an acceptable interchange for a drum car, the residual valves notwithstanding?
2. What are the spec differences between the early and "late" manual drum MC's? The books call for different part numbers.
It amazes me that 3 different cars had the wrong master installed. Is there REALLY a manual drum pre-'71 or so master or do they truly interchange with the power drum cars? Sorry for the long post but there is a lot of confusion on this. Thanks!
