It appears those playfields are missing more than just dimples, Ron. Not only were dimples added in house, but so were many post holes and the like. I've never heard why this was done.
If the Addams is like most NOS I've seen in the past, it'll be missing somewhere in the neighborhood of 50 holes. Fifteen of them are for the pop bumper bracket posts alone. There appears to be no holes for the posts around the electric chair either.
Looking at the BSD, that one might be fine.
You might want to double check them all. I'd hate to have you go through the work of clearing them only to find out later, you need to drill some holes.
BTW, amazing buy! If I had had the chance, I would have bought them all too!
