I found this and looks like it can hold a cb70 tub nicely. Trim down the poles to what height will be needed and should work out right? Its got the dimensions there. My tubs are 17 3/4x33 1/2x6 1/2 tall.

check this out, it should help

I guess it would, but would be a real tight fit and you might not be able to get it in and our of the rack easily.
