Looking forward to seeing it
I did wonder on the earlier photos how you were going to brace the front and rear, i have always thought if you can do it is to have a high wall at the back and slots for the wishbones to hang out of, i.e. the tub wall carries on until the very back of the car, and simlar at the front.
A bit like this

Would be such a clean design
