Shawn, I have an idea similar to that for the radiator support that wouldn't involve hacking up the original, I'll snap a few pictures when I get around to building it here soon.

I'm not sure yet about the rear rails. They are pretty tall and I thought about tapering them down towards the end.

I was hoping to get the 440 installed last night, but I had to cook dinner, then put up the Christmas lights on the house, and ended up cleaning the garage. Maybe tonight?
