I think the 62 and 63 MCs are Wagner, not positive. The 64 might be a Bendix. The look of the MC is different between the 63 and 64, but could still be the same manufacturer. I believe the only difference is the shape/look and line fitting sizes. That's all I can remember anyway. The brakes were excellent on my modified Americans. You are 100% correct! Except for the exterior skin, firewall, and dash, the car IS a 1950 Nash Rambler. Glass will all interchange with the 50-55 models. The 58-60 has only minor revisions to the 55 facelift. The 58 American is the only car in US history to ever be discontinued then reintroduced successfully as a "new" model. Even the L-head engine was reintroduced with it (no L-head for 56-57). Great parts interchangeability, even with some of the pre 63 big car parts. Lower trunnions and control arms interchange, but upper trunnions are different on the American (I believe the arms are the same as big car though). The only difference in the control arms is the size of the rubber bushing. The fenderwell "humps" are left-overs from the 50-53 front suspension design. The panel under the fender had a hole in it and a conical "tube" for a reinforcing rod to run through to the under hood fenderwell panel. That was eliminated when the upper shock mount was redesigned, but the underhood panel stamp was never changed -- no need to. -----Original Message (edited)----- From: Tom Jennings [mailto:tomj@xxxxxxx] Sent: Monday, April 30, 2007 12:38 PM > I also installed the Classic dual master cylinder and rear > wheel cylinders to complete the transformation. Any mods required? Other than line position/fittings? I still can't figure out what the difference between (say) 1963 and 1964 American master cyl is. Don't nobody take this wrong, but this car isn't very AMCish in some ways -- I assume it's the 1964 redesign that brought more of it into the across the board parts interchangability. It really is a 1950's Nash under there. Which makes it more interesting in some ways. The 63 American may be the newest oldest car of the 1960's. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
