Why not give BMR a try? I met the owner of BMR a couple of times while hanging with David Piercey, a well known local mustang mechanic who built the BMR shop building on 301 and unless he sold it, David has a large shop next to it too. It's been a while since I've been over there...
The BMR owner seems like a stand up guy IMHO so why not at least talk to them and/or give the BMR shop a visit? I do not have any personal experience with thier stuff but I can say what I saw looked top notch as far as welding and powder coating was concerned.
Might be worth a try since you can drive over there to discuss any issues you may have with the parts/install instead of an email or phone call whatever.
My humble 2c.

Must be nice to have the resources to buy a new '05 and tear it down....
