has any boby fit or modified a dizzy from a 351 Windsor sb with electronic ignition for a yblk  ??? or would it even work  or does it rotate in the wrong direction   

Yep, it's been done.  Do a search for duraspark and quite a few topics should come up.  Here's one to get you started.

The expert that Cliff is referring to is Steve Metzger aka "Greenbird".  If you want to do a Duraspark conversion search out his posts.  You won't be disapointed.

What is the advantage to this conversion?

I converted mine to Duraspark on my 57 Ford 292 a few years ago. Starting and idling were greatly improved on mine and runs great driving down the road. I picked up the factory wiring loom when I gathered up parts to do the conversion so the installation looks almost factory installed. Haven't had a bit of trouble with it out here in the AZ. heat. X2 on Greenbirds knowledge on this conversion.

The biggest benefit, if you stick to Duraspark, or Duraspark / GM Hei hybrid, is that you can find replacement parts practically anywhere.
You can also use the Duraspark distributor components to trigger pretty much any aftermarket ignition box.
