----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----Byron; It depends on how much, if any modification was done to the original seat supporting structure and seat belt structure/hook up. The original seat back frame and seat bucket combination, had two bolts at the top which fastened to frame D at the window sill level, four screws, two in the bottom of the back frame, and two in the bottom of the seat bucket, which fastened to the Vee braces on the floor, two screws which fastened the inner window protector skins to the outside of the seat back, and one or two screws into the top center of the front spar cap. That part is easy. The hard part may be however the seat belt hook up was done. The original seat frame had two triangles which bolted to the back of the seat frame on the wide end, and to a 1/4 inch steel rod in the rear on the other end. Each steel rod then went back into a steel fitting, riveted into the belly behind frame E.
Confused yet? >grin< If you have all the pieces, it would be just one days good work to remove the Cessna seats, floor pan, etc., and install the original Coupe parts. This is all not counting any upholstery work. Does your coupe have the large baggage compartment installed behind the Cessna seats?
An important question, how does the weight and balance work out with your Cessna seats? The modification moves the original CG aft some, but the kicker comes in when you figure the center of the Cessna seat. It is 7 to 9 inches aft of the center of the original. So you will lose some leg room when you convert back.
