Hey I hate doing this,but I searched,and can't find an answer to this question. Maybe I am not searching right,but here goes anyway. I have three spare dizzies,and I think one is from a GSL-SE,but I am not sure which one. Is there anyway I can determine which one is a GSL-SE dizzy by appearence? Is there a part number stamped into it somewhere that will tell me which is which? Sorry if this has been covered,but I couldn't find it.

 

Anyone? Bueller? Bueller?

 

GSL-SE has curved advance slots vs straight for 12a, giving maybe a few more degrees of timing advancement. Not really all that worth it.

 

I think the amount they advance may be the same. The difference is when in the RPM range the advance occurs.

The GSL-SE will have the curved slot which you can see if you look through the openings in the moveable plate under the pickups. Also you should see N304 on the dizzy housing. The 12A units will say N201 or something with a 2 in it. (2 = 12A and 3 = 13B - easy as a moon pie to remember).

 

Thanks guys,

Jeff where will I see this stamping on the housing? The narrow part that sits inside the engine,or elsewhere? Thanks again.

 

The outside where the other numbers are.
