WelcomeChuck,
If you still have the base on the floor where the cooler sat (or even the shadow that showed where it used to be) I think I would measure and see what you can find to fit, regardless of the capacity. Some of the coolers are tapered sides and some are straight.
If t here wasn't a base then I would measure the width of the console and it you can, and having a full width cooler in front of the console doesn't impede travel fore and aft, buy one that size.
