It seems the sills were replaced. I'll take off the outer sills to be able to inspect better.
The box sections across the bottom of the car was replaced from the longitudinal member and out. So was big parts of the floor. If he took out all of that at the same time without any jig, Murphy will be very busy! I'll have at least to cut those at one maybe two places and take out pieces of the floor. That will make it floppy again. If not, I'll have to cut more places. The box sections are good, so need not be removed, just weakened where they meet another section.
What worries me more are the reverse curved surfaces. If you look at the parts I made for the bootlid, they are compound curves. Like a bowl. Fairly easy to make with a bit of patience. Put a bit of sheet on a purse filled with sand and hit it many times with a mallet and you have a piece of lumpy bowl shaped scrap. Planish it over a dolly and you may have a body part after some training.
But the wheel flares make a reverse curve against the fender side. An example of a reverse curve is a saddle or a potato chip. They are not easy to make by hand. If you make >1000 pieces you would stamp them. But that requires heavy and expensive tools and dies. I can't really tell how to make it by hand, because I don't know yet.
Tell me Raymond, the box for the air horns in your right front inner fender, how is the bent trumpet shaped section going from the top spring seating back to the firewall arranged? (can be seen if looking in over the wheel) Is it just cut?
And I may go for sky blue if that is what I think it is, a fairly light blue. But there will be lots of time before the top coat goes on, so there will be opportunities to see it in real life. I think that's the color on a spider not too far from where I live. I just have to be there the day it is outside the garage.
