Gran Bateau interior transom panels

[GRANBATEAU]

Last year I purchased a 1978 Cruisers Yachts Gran Bateau to rebuild. All has been going fairly well. However, I cannot figure out how the upholstered panels go on the transom inside the boat. There are 2 panels the full width of the transom (72") and each about 12 inches high. There are also 2 panels which essentially cover the lower part of the transom from the floor up to top of the engine cover (these I know where they go). There are also 2 other slightly similar panels which I do not know where they go. There are also several seat cushions and backs of which I know where they go also. I contacted the manufacturer as well as several of their franchise owners but they were of no help. Would anyone have any thoughts or ideas as to how these panels fit or have any pictures of the panels in place on another 1978 Gran Bateau?
I really appreciate any assistance or suggestions anyone would have.
Thanks so much.
