I recently bought the hardtop cab made by Original Cab directly from the company. I paid more than the ad on the other post but the company was able to answer some questions about fit for my
BX23. I ended up fabricating a brace for the rops..other than that it is a good fit using all factory holes...did not have to drill my tractor! I got the optional winshield, wiper, and lights and mounted an interior light and strobe on the roof. I did not like the white color and had the body shop paint it to match the kubota. I did not add heat, but that has not been a problem as the wind and snow are off me. Also no problem with fog as I left the air flow thru the grill under the steering wheel and the air flow seems to keep things clear. The problem I had with the solid cabs was that the rops would have to come off wheras the Original cab is in front of it. Secondly, seven bolts and it can be lifted right off for spring.
