This may seem basic to a lot of you, I have a 1929 A and I am replacing the ignition switch. My question is "does it matter which side of the ignition switch I connect the power to" thus connecting the cable to the other side?
If you have a question about your car ask in one of the forums. There are 4 sections Model T, Model A, Early V8 and Late V8. The posting on those 4 is more directed to stock type cars and trucks.
If it's a customizing type question try; http://www.jalopyjournal.com/
If you have a 32 to 34 4 cylinder engine question try the Model A section.
