This morning II started to attach the right cabin door by using a Dremel to level the area where the hinge will sit. Note to builders. For the right door, WD1018L is placed in the aft detent and WD1018R is in the forward detent. This is opposite of the location for those hinges on the left side...but I did not see it in the instructions. Killed an hour figuring that out. Once they were in the right place for the right side, I squared them up and tested them for binding. They were very smooth so I drilled them in place. The .125 spacers on three sides really helped keeping the hinge in the middle.
