Completed installing seat back and seat bottom cushions. Very difficult to stretch cushions over frame. Had to tape front corner of seat pan to prevent edge catching on seat bottom when installing. Also had to stretch (widen) base of seat back using long clamp to remove and install seat back support tube when fitting in the bottom pocket of the seat back cushion. Headrest cushions installed and set aside. Also, inventoried and arranged Finish Kit hardware on parts board.
