Slide alignment problem after awning hangs

Well, the bolts didn't sheer. I don't think the could. Keystone put in the wrong bolts. They're over an inch too long and are threadlees on the part that goes through the hole in the shaft. And they're too big. They had to pound them in with a large hammer. One they got all the way in. They other came up a quarter inch short. It was hard enough just getting the nut off because the threads were slightly damaged and rusted. Now I'm hoping I can get at least one out. It's wedged in so tight that I couldn't get it to budge with a regular hammer. Any ideas will be appreciated. If they had put the right bolt in, I doubt I would have this problem. It looks like there could be some minor damage on the hydraulic side. I always assumed the damage would be on the other side since that's where it got hung up. But now that I think about it, all the force outward was on that side. If it jumped the track, maybe it did there. My phone battery was dying and I couldn't take pictures. It will be easier to show you what I mean. I can now see how it might have gotten off track. I'm hoping that if the other side is made even, it will track better on that side. I'll see if I can get the bolt out tomorrow.
