So I scored a OEM factory cab door for $200.00 yesterday for our 743. It's in decent shape. I'm in need of the panel that bolts in underneath the door to fill the void on each side when the door is on. I have looked and looked with no luck. I also need to two pieces that bolt on the cab frame that the door hangs on, and the striker. I'm more than likely going to make some side windows out of lexan or such since finding the OEM glass tracks, etc seems to be next to impossible. Thanks in advance for any info!
