Hello all. After plowing snow last winter in my father in laws 743 with no glass in the cab, I'm going to fix that issue. I can get my hands on some good lexan to do the top, rear, and sides with. I'd like to try and find an original door if possible. Id even be happy with just the frame of a original door. I haven't been able to locate one anywhere though. I was also thinking that I read somewhere on here quite awhile back that a door off a older Cat 226 skid steer will also fit a 743. Either way, if I domfind a original door, which I hope I can, obviously the door won't cover the two lower areas to the right and left of the tilt cylinder. The area where you step out. I'm curious what is supposed to go there. There is factory holes drilled, so I'm guessing there is pieces that bolt in there? If anyone knows or has ideas of what I could do it would be much appreciated! Thanks, Kyle
