This is a cabin frame I bought yesterday, used with the steel framed doors which were canvas covered. The friend I got this from was possibly going to cut off the extra metal piece at front, where the doors fit onto the two pins, and use with the standard doors. Couldn't let that happen. So, with assistance from Rob P., and the measurements he sent me, I will need to make yet another jig, this time for funny looking door frames.
The sunshine cab roof and canvas door cabin will both be going onto my grey truck.
