Man what a pain in the ass this has been. Whoever had the truck before me had a 5er in it but took everything out ( except 1 bolt that's rusted into place in the frame....thanks asshole).
I've been looking for a 5th wheel hitch that matches up to the existing holes because I don't want to drill a shit ton more holes in the truck. I've asked people at the duramax board, local people, and people selling hitches online. No one was any help at all really and I don't blame them but would've thought someone could've helped me figure it out.
I think I finally figured it out today. Here's a picture of my bed so the rest will kinda make sense.

I found a reese 15k slider on ebay for $525 shipped which is a pretty good deal. I asked about the rail bolts and they were different. They had 2 bolts per rail instead of 4 per rail like I have in the truck. The guy had no idea why they were different. I stopped to get fuel today and see a dually there that has a hitch in the bed. I asked the guy if I can check it out and he says "no problem". I look at it and it's the same bolt pattern that was in mine and it was a Reese so at least now I know Reese has a 4 bolt per rail kit.
Went to U-Haul today and of course there was a lady behind the counter that didn't know shit but she called one of their other stores and I talked to a tech there. He was no help. Just told me they'd install one for $900. Thanks asshole but I don't want 16 more holes drilled in my bed and frame.
I come home and start searching Reese's site. That's when I got it figured out I believe. It's a universal Reese rail kit without the center bolts installed. Now why couldn't 4-5 other people, some of whom do this shit for a living, not figure that out or at least recommend that that's what it might be? I contacted one guy through ebay and he says Reese doesn't sell those rails with the 15k slider anymore. Another guy said they have one at another store and he's supposed to get back with me.
Would've been easier if there hadn't been a hitch installed at all and I can only imagine how fun it's going to be to get that rusted ass bolt out of the frame.
