Crab Dist point conversion ??

[V8guy]

I have been doing flathead distributors for myself and Badger State club members since the mid 70s when I purchased a Sun tester from the Sun rep while working as a tech at a local Cadillac dealer. The other day a member brought his dist over for me to check, never seen a point conversion like this, he has had the car over 15 years this is the first time he had it off.
