Mallard 29F slide out adjustments

[chamaman]

I just finished repairing dry rot in the header over my 1999 Mallard's slide out. It was discovered when I took it in to a large repair facility. They had to remove the slide out completely to inspect it, so, when they told me it would cost me $9,600 to repair it I had them put the slide out back in and brought it home. After 34 days of off and on working on it I finished repairing everything and I must say it looks great. The problem is now that I've got the Slide Out back in I need to adjust the vertical and horizontal positions so it will slide in straight seal tight. I would like to find an adjustment manual or someone that can give me some instructions. At this point there is a 1 inch difference between the front and rear of the slide out and the trailer. If anyone can point me towards an installation manual or just has advice on how to adjust it I would certainly appreciate it.
