Does anyone make one with an eccentric offset so the drain position can be adjusted a half inch or so in any direction without re-plumbing?
However you could install a 4x3 closet 90 with 4" closet flange, and within that 4" opening you could shift the bowl around.
I like the flanges with metal rings over the plastic flanges. Sioux Chief a TKO with a nice stainless ring. That comes in a 4x3 though.
They sell a flange extender too, that stacks the flange higher then the subfloor. It's a spacer that goes under the flange.
