I am working on a 69 Roadrunner (with a 440)...the vacuum advance is shot and needs to be replaced and the only information I have is from the inside C15 and 6.5 (maybe 0.5) on the arm. Anyone have any idea where I can find a vacuum advance that will fit. Also, I am new to MOPAR and hove no idea where on the 440 block to look for a casting number to see what year the motor is from in case I need to buy a whole new distributor, etc...could someone please tell me where the casting number of the motor is normally located?
