Kevin there is an “A” motor mount on eBay now by itself.
Go to Auto parts and search Mustang II motor mounts.
Says $300 but it’s eBay, make an offer.
Looks like you found a bunch of “B” mounts.

Classic Roadsters Used The Drivers On The Passenger Side And Vice Versa.

The guy at Classic Auto Restorations, who has the rebuild kit, says the Mustang II mounts are one off parts that’s why they cost so much.

You can easily chop/reweld 3/4” off the bottom of the U piece in the frame brackets to lower the motor for intake clearance and get on down the road.

Upgrade to new mounts later and sell the Mustang II mounts then.
