1968 ac vent how to remove

5/16, 3/8, 7/16, 1/2? bring a set

Deep socket.

1/4 drive would be easiest but 3/8 probable would work too.

There is no physical attachment from register to heater/ AC box just foam seal.

The hole in the chrome strap is 0.70" dia and 1.5 deep. You DO NOT remove the chrome strap, it is held in at the top by 2 screws you can not access till the register is off the dash.
