Try the guys at the westerville oreilly's. They might be able to track down the body parts you need. Talk to cody that works there about the paint work, he's been doing body / paint work for a while and he's good at it.
Tell them Leigh sent you.

When i cut the brackets off of my 8.8 i used the solid 40 grit grinding wheels that came from harbor freight then finished it off with the flapper sanding wheels.
Heres how mine turned out.

this thing was real nasty too as i pulled it from an explorer in a junk yard.
One thing i have seen guys do is shorten the drivers side tube to match the passenger side tube and then you just have to get another passenger side axle instead of a custom one. This will also center the axle for you.
I paid 55 shipped for my Tial knockoff, I think I even found it on evom. For what you're doing dover just get the 1g dsm bov. They are good to 25 psi unmodded.
