breakerless dizzys

anyone know if theres any internal differences between the 12ST dizzy and the 13S dizzy, can they be run on each engine, no problems ?

if i remember they are the same, but any differences will be in advance curves and bob weights, which will probably make no noticable difference to an engine which has fueling issues.

agreed on the dizzy, the internal differences will be very small. back in the dark ages, i used to get them from whatever car was nearest in the scrappy's
