for those who did reply to my post
Man, I love forum politics!
Anyways, just saw your line about - "will run, won't shut off" - This is a problem I've had with MSD ignitions before. They somehow feed themselves enough power to keep running with the key off through the ALT light circuit. You need to add a little diode - Google should tell you the specs. On Fords, you turn the key off and then hit the brakes - the power drain of the brake light kills the motor, it's a fun party trick.
This may or may not be your problem.
