looks good ,ill give you an idea that will help the keep it structurally strong ,and make finsih work alot easier on the side pieces run a 1/8th groove about 1 inch from top of edges and staple it into that groove so when your ready to wrap ,the hardened fleece or material isnt sticking out ,and you can just lay foam over it and wrap ,and call it a day same for if you mudd and and paint it or you can take 1/8th inch hardboard and make same contour deisgn and lay on sides ,if you wanna paint top and keep sides to match material in vehicle ,hope that helps a lil
