Hellcat716,
How much did you reinforce the firewall? I thought the firewall was kinda of flimsy so I pulled out the hot melt (very easy), and am now making a piece to duplicate the cross shaped reinforcement out of 3/32 aircraft ply. I plan on glueing in 3/8 triangle stock in 1/2 sections around the perimeter of the firewall. That is the only thing I see that that looks kinda wimpy other than adding glue here and there.
