66 Barracuda radio wiring

Another question, what size condenser is attached to your coil ? My car came with no radio so none of these things are on it.

I appreciate your response.

Those are not at all critical. "Get a good parts man" (Yeh I know, hard) and insist that he (she) find a numerical/ pictorial guide if they don't know. Just ask for a generic radio noise suppression cap for the coil. I think Standard were "obvious" part numbers such as "RC-1" and "RC-2" or some such

An example from Summit this price is preposterous

Standard Motor Products RC15

If you have a cap kickin around out of a distributor you could use that as well
