MSD custom advance bushing sizes

I think the mopar dizzy could be modified to be adjustable with a bushing as well. First the slots would machined wider and made as long as possible. Then I would drill and tap the post on one of the weights so a screw could be used to hold the bushing to the weight. I think you would only need to do this on one weight not both. Bushings could be made for any desired advance at this point. Once I get my hands on an old dizzy I'll build a prototype.
