All pro flatbed kit
 

I'm trying to find a solution for a bed for my truck. A clean box seems to be really hard to find, and expensive if it's a good one. As an alternative, I do really like this all pro flatbed kit, but it looks like they don't sell it anymore. Does anyone know where I can find that kit or a similar one? The only other one i've found is the trail gear kit here but it has kind of a goofy look to it in comparison. I've seen the flatbed ideas thread, but I'm looking for a pre-bent weld in kit if possible.

I'd first call All Pro and inquire to see if they can make you one. Might not be listed because it's not something that moves off their shelf frequently. Any other fabrication shop should be able to fab you a flatbed to whatever spec you want. Otherwise, there's always the DIY option if you have a welder (assuming so, since you want a weld-together kit) Another option is fiberglass bed.
good luck!

Good call on contacting them. I shot them an email about it and this was their response in case anyone else is also looking at their kit.

"Hi there, We are reproducing it right now and it should be ready here in about 2 to 3 weeks."

Even if they weren't putting it in production, I wouldn't think it'd take them a long time to put together a kit for you - the bends are pretty simple compared to something like the TG kit.

You may consider calling up a few fab shops to get quotes from them, installed. It's possible that you may come out ahead this route (once factoring in install time/labor) and get something custom.

good luck, let us know how it goes!
