choke for Holley 1 bbl

Correct, it doesn't matter that it's listed for a Carter. When you get it and open the box, you'll find a Holley choke inside.

You'd still be far better off with the electric choke kit I linked. Kit number 1231. You will regret not buying it the first time that '73 truck choke isn't quite correctly calibrated and there ain' nothin' you can do about it. Just saying.
