Dave I fixed the dizzy today; I used a scrap piece of Lexan, I used then the 3 blade metal part on the underside of the advance plate as a pattern. Works well and the air gaps between the reluctor and ring are pretty much perfect.

I should have made two pieces becuase when I popped the cap off the distributor from the spare A15 low and behold I immediately saw the little BB lying inside. Obviously that one as an issue as well.
