Very nice job. Looks very similar to a used cab I purchased from the local driving range; suicide doors and all. It was used to pick up golf balls at the range and had expanded metal welded to the cab frame.I bought the cab - more like a cage, for $50.00. After cutting away HUNDREDS of spot welds to remove the expanded metal, I was able to fit it on my B1750. I skinned it with orange poly on the lower half and clear on the upper. No heat, but all I need is something to shelter me from the wind. Worked well last winter.
Looks like your cab is coming along well. I was actually on kijiji the other nite and seen your add for your other cab. But i think sooner or later i will just take the time and build a cab. More time than anything really.
