Can you do me a quick favor and measure the distance from the center of the inside mounting bolts... When I measure on my BX2230, I get about 23 1/2"... I'm trying to see if I can buy a "spare" SFBX-23 and use it as the base of a cab project I want to start. That way, I can have solid mounting points on the back of the tractor and be able to take it on and off with summer/winter.
