Thanks Mark, I'll have to look into it.
I did order one from Southwest speed, should be here Friday. They are a race-car supply company, so I expect it to be of decent quality.
I stopped in 4 local parts stores, they had less info than I did.
I called The Parts Place...no info. PY has one made by Packard (never heard of them), and Ground up sells the Rare Parts one for $129, which is a good price.
I often buy from the other A-body suppliers. I see several vendors at the Carlisle swap meet....Ground Up, Lutty's, Fusick, Ames, and Performance Years. I get the chance to see the products before I buy and save on shipping costs.
