Will be installing a #10 plate, 3k GSK and AFC kit tommorow.

There are two springs for the AFC kit, should I use the light or medium spring?
As I understand it there are two sets of three springs in the governor.
Am I correct that I should remove the small and middle sized springs, seats and any shims, and replace with the one's in the kit?
I leave the large springs and any shims for them alone?

Any install tips for the Plate, GSK and AFC kit is appreciated.
