Adding an electric jack to 2005 Bambi -- what diameter?

[platbr]

I'm looking at a Barker Hi-Power 3000 lb. electric jack for our 2005 19' Bambi. Our Bambi has a larger jack hole top and bottom, with a smaller "collar" bolted down below. Without pulling this entire thing off (again) before ordering a new electric jack, it is difficult to tell what diameter jack I should order -- 2-1/4" or 2". It seems like either size might work with the collar off or on. Anyone done this mod and know the right size to order?

Thanks in advance!
