Looks like the Corsicana, TX supercharger is getting an upgrade and expansion similar to the Waco, TX supercharger. There were 6 of the old stanchions, looks like this is expanding to 10 of the newer style ones. In the 1st picture you can see 2 of the new stanchions leaning against the supercharger cabinets. In the 2nd picture you can see 6 of them leaning against the shipping crate. Then there were 2 of the old ones that had already been replaced with the newer ones. That totals 10.
