I looked everywhere in the 1973 Buick SHop manual. NO where does it say which of the towers on the distributor is the number 1 tower ? Does anyone know ? PLEASE tell me. THanks Gary
#1 is on the left (clockwise) of the adjustment window. There is a picture of this somewhere on this siteuzzled:
You can turn that distributor body around all day and make up your own #1 spark plug terminal. Where the rotor is pointing at at TDP of cylinder #1 (with both the valves closed) can be your spark plug #1 terminal.
