Unlimited funds, huh? Hell, I'll take a whack at it.
Seriously though, I saw an article a few months back in MM&FF that got me to thinking about this. The company took a Cobra and completely chopped it in half legnth wise. They widened it by 6" in the front and 8" in the rear. No bondo was used, everything was welded. The company was out of California. Ready for the kicker? I can't remember the company name and I no longer have the magazine.
If anyone has back issues on here they may be able to help. You could also try a search on MM&FF's site for the article.
