elm2627, I have that setup. The Accel / HEI In-Cap 1991-1973 Super Coil With Red And Yellow Primary Wire Part #140003. I bought mine from Autozone. Any of the local o'reillys, checkers, autozone,etc should have them or order it for you. Check on Autozone.com and do a search on the part no. (or look under performance parts/ignition) It should give you a picture of what you want.
