Just so you would be able to mount the inserts easier, or ot even needing them; how would the inner wheel wells look if you when you bring them up, just continue going back to the firewall for a flat design look (almost stockish). Something like this:

I thought about doing the back part and I'm kinda scared you almost read my mind, however, there is something else I will need that space for in front of the "tubs". You will notice I have only tacked these in for now. You all should know me by now this may not be permanent I even have the cardboard cut out for the rear part filler
