I see "Cletis" as a moderator of this section and hope he is looking in. I'm having a prob w/brakes.Not fully releasing that is,I suspect the master cyl is defect. If I have to get into brakes,I'm going whole hog.I've Read Cletis Hardins tech tip and wondered if this dual mas cyln swap out can be used on a '52 3100? or was he referring to a later year GM Product?
