Started installling the right door. Doing it on the plane seems to be the best mode of opperation. We started with installing the outer top door frame then taping the inner door support frame in place with masking tape. the plexiglass is easily held in place by a few spring clamps. A block of wood was used to hold the taped parts in place while drilling the upper holes first. 3 inch spacing seemed to me to be the best . The instructions are very specific about which holes to drill first and in which order to avoid buckling of the plexiglass on the frame.
