This is where one of the bulbs mount, fixed the ad, thanks.Your numbers don't match. (Ad vs picture)
Anyway, I repaired the circuit board on my old 69 Coronet. It had a burnt out spot. I was able to solder a jumper wire across the damaged area, and it was good to go.
I have a circuit board in my garage, needs a pin replaced though. Plus, mine is for a 68-70 I believe, not sure what year you need.
