Hello All....I am a new member and am looking for some info....I just purchased a nice 1963 rambler classic 660 with a 6 cyl engine and lost the distributer on the tow home (previous owner left it on the battery tray)...am hoping to find out what years will work and from what engine sizes....also firing order, and if this distributer is the same from another make (ford, gm, mopar) I know amc used various other manufactures parts....also what bolt pattern would the bellhousing have?...is it amc unique, or the same as a gm, ford, mopar application....does anyone have a dist for my application?....is there an HEI unit that will swap in nicely? (already tried a 75 gm hei from a 250 straight 6 cyl....fits nice, but the drive gear on the distributer does not reach the cam gear..)....also, any idea what gear ratio would be in my differential?....Thanks in advance....you can email me at fasted44@mts.net Ed
