I'm thinking it may have hooked into the Duraspark II system somehow. Or perhaps they were used with that variable venturi carb, the 7200.
Mmmmm, looks like something that comes off my Dura Spark mod. I have no clue what it dose. Anytime I have unplugged it, the car did not run funny or any different that I could tell.
Mr. Gasket sold Dial-Advance at least 40 years ago, nothing new, old-old cars all had it. My friend made his own timing adjustment device, cut a hole in the firewall and reached through and turned the distributor to advance or retard the timing while going down the drag strip.
i had a car once that the timing was giving me a fit so i hooked an old choke cable to it so i could adjust it on the fly. once i set it right i just locked it down and took the cable off. it was a 74 monte.
I used the choke cable also on a '81 c-10 I put a 327 in back in high school. Reason I had to was because I over tightened a rocker arm and rounded a exhaust lobe on the cam (at 17 this was my first experience with this) so if you got the timing where it would run good, it was hard to start. If the timing was where it started easy it would pop and spit through the carb. My dad showed me to retard the distributor to start than advance it after it started so we run the choke cable to it...pull it to start, push it in and run like hell
