Would it exist on a 1979? Should I buy it?

EDIT: if I buy that and this... http://cgi.ebay.com/ebaymotors/GS550...Q5fAccessories Can I eliminate the points?

Reminds me of cdi unit that I put in a 64 Mustang! Looks like someone is being electrically creative.As for the other part ( plate with signal generator coils), you'd also need the advance mechanism that mounts on crankshaft and activates the coils. You be safer with a kit that includes all the needed stuff.

First auction is to an ignitor. Looks like someone took a different model ignitor and grafted on a GS harness plug so it will mate up. Looks sketchy. In order to make it work, yes, you would need some signal generators, plus a magnetic rotor to trigger the signal generators. For $120 you can get yourself a brand new and shiny Dyna-S ignition system that will have a warranty and everything. No brainer unless you have a parts bike with all the conversion parts at your disposal...or if you are really tight for money...in which case you should just stay with points.

Get a Dyna-S, worth every darn dime. I did not like having to check points, timing then replacing em every time they wore down. I put about 100 miles a day on the bike it would not take to long for me to equal the cost of a dyna.

The Dyna take about 15min to install and time. Works perfect and I never have to worry about my timing being off again.
