Spent the evening trying to put the seat and the upper surface of the fuselage in their best orientation. Harder than it seems it would be. Very little guidance from the plans except that Ray Stits' seat height was 6" from the bottom of the tubing. Met him once at Oshkosh, he seemed like he was a little shorter than average. Hard to imaging altering the dimensions if I get it wrong. Wish I could figure out how I could sit in my AC and check. Got some parts from Aircraft Spruce but spent fully half the cost of the parts getting them here. Going to have to find some local suppliers near Columbus.
