12a dizzy vs 13b dizzy

do the 12a's and 13b's use the same dizzy? can I put one from a gsl in a gsl se, or vice versa?

technically, someone posted that the curves are different between SE and non-SE.

However, I've tried both and didnt notice any difference at all.

The only different one is the 12A Turbo one.

Here are the advance curves for the 2 dizzys (from '85 FSM). Either one will work though. I currently have a 12A dizzy on my SE and didn't really notice a difference between the two. You will notice an error in the figure. It lists the engine rpm has 1/2 the dizzy rpm, but it is really the other way around (2000 dizzy rpm = 4000 engine rpm). The curve shows (when you correct it) that full mechanical advance occurs at around 4000 rpm (engine).
