1982 GS1100G - Convert to Mechanical Advance

[Guest]

I have a 1982 GS1100G that I am trying to concert the ignition to a DYNA-S. I am assuming I need to convert the electronic advance to mechanical. So 2 questions:
1.) Can anyone recommend a year/model Suzuki that has a mechanical advance unit I can use? I am assuming an older 1978-1981 GS1000 advance unit will work?
2.) I can't seen to loosen the center Socket Head Cap Screw holding the signal generator assembly in. Can anyone tell me if this is a standard thread and it's just stuck or if it is reverse thread and I am turning it the wrong way?

Not sure if this helps or not in your situation but, one of my '82 GS1100G's started out as a bare frame with a damaged engine to go with it.
The ignition and wiring harness were absent so I stole the complete ignition system and wiring harness from an '81 GS1000G parts bike and it has been running like that for several years.
If you like, I could take a picture of the 1000G advancer/rotor in the 1100G engine tomorrow. No Dyna ignition parts though.

Thanks guys, both posts will help. I think I'm going to try and get a GS1000 mechanical advance unit and give it a shot.
