I am going to attempt to replace my points with electronic ignition. My question is when I tune it where are the tuning lines when adjusting advancement. I don't see any obvious lines. It has been a long time since I've done my own tune ups but I do recall spotting the timing light on a line on the main belt assembly and advancing or retarding the distributor until the lines line up. Am I in over my head? Could be fun anyway.

Here are two pics the electronic is in my convertablie and I had it done. The points are in the Mach 1.
