Pace Edwards Full Metal Jackrabbit - pain in the....

Ok - so today I picked up a used Pace Edwards Full Metal Jackrabbit retractable tonnaeu cover. It's a slightly different design then the current model in the bed rails. And the instructions are, well confusing. I got it on... but I know its not quite right as the tail end of the rails by the tailgate, are too high and are above the tailgate.

On each rail are 2 vertical sections of metal that appear that they should be between the mounting-rail and the clamps. But If I do that the space is too tight for the cover to move, and I can just barely get the bolts on (no space for washers). So I ended up moving the tonneau rails up /out some with the vertical parts resting on-top of the mounting rails. (which spreads the gap out by 1/2 inch but makes the tailgate end 1/2 too high).

So has anyone successfully done this? (or understand what I wrote - it's dark out no so pics, I'll get them another day.)

I am considering a couple of options:
1) leave it - but it's not weather tight or secure
2) Try again and ratchet it way down in hopes of making space
3) 'adjust' the vertical metal bits (via hammer) (it looks like they are screwed in but I didn't see any adjustment)

Thoughts?

(btw - these are going on 2007 DB short bed)

Thanks,

I installed one the other day on a Chevy. Did not have much of an issue after sliding the side into the big box up front.

A picture in this case is worth a thousand words cause I am having a hard time imagining what you are talking about.

The railing should be on the inside of the truck bed and the flat piece should be flat with the bedsides. The only "adjustments" that were sent with Chevy kit were little black pieces which were about 1/8" thick each.
