Jay 2 things, the magnet in your dist looks like it took a hit from the reluctor fragment . Is that a problem? Next now that you have proved the clear valve covers work in the real world WHEN can we expect full on production! Just kidding. Sounds good. As for gremlins I`ve been hammering on the Harley bobber I built for the last few weeks to get ready for our roar to the shore in Erie PA this thursday. Finally got all the leaks and driveline issues sorted and got 100 miles on it last weekend. Now their calling for rain thurs -sat during all the fun. 
Garry that's a great observation, and when I took the new distributor apart and saw that, I thought that the problem was the magnet, not the pickup, because the magnet was cracked in two. As soon as you break a magnet, the pole structure changes, and I thought that must be the problem, especially since the pickup showed the proper electrical resistance. However, when I took apart the old distributor to take the pickup out, the magnet in that one was cracked also! So much for that theory; I wonder if they tend to crack on installation, when the bolts are tightened or something. Anyway, I swapped the pickup from the old distributor into the new one, and kept the new one's cracked magnet in place, and the distributor worked fine. So, no doubt it was the pickup.
Assuming the valve covers last the summer with no issues I would expect to put them up for sale in November.
