Modified 4 AN 3-21A bolts per plans for hinge pins.
Using plan pictures paired up hinge segments as the peices weren't marked. Placed hinges on cabin cover and using 3 X .125 spacers, drilled one one on fwd and aft hinge. Inserted hardware and useda straight edge to draw reference line on cabin cover. With hinges correctly oriented to ref. line, match drilled remaining three holes in each left hinge.
