Actually, if I change it, I'm on record as saying that I would go with P1 stuff, and I still think that's what I'd do.
I took it back to one of the places that gave me an estimate and he is 99% sure there is no core support damage.

I'm going to take it to that place in Sac that ScottB recommends and see what they say as well as have Nate take a closer look (what we thought was a broken weld may have simply been poor use of adhesive during assembly).
Stay tuned for updates. I'll actually be glas if there is no structural damage because that means I can get non-stock parts and make a little cash off the deal. Otherwise, I'll just be out of a car, probably for too long to make it to buttonwillow.
