Wheel and Tire Help

Can those who have done this before look this over and let me know if this seems right?
Thinking 18x9 with 275/35/18 in front and 18x10 with 285/40/18 in rear
Barracuda vert, QA1 kframe with hotchkis upper control arms and B-body Dana in back
Here is the Forgeline measurement sheet my builder came up with, seem accurate ?

Well, your chart doesn't list any backspacing for the wheels and it doesn't appear that any cycling of the steering was done? Straight ahead is likely to have more clearance than at either lock. Did they check that?

When I was testing fitting rims on my 51 I had to sort all that out myself. I came up with a way to do that easily.
