All wheel trim tonneau cover problem

Hi all,
I've just invested in a tonneau cover from all wheel trim for my truck cab, now does anyone know how to fit it? The back and the sides are straight forward although the eyelets don't line up properly with the front 2 cleat things. But the front just doesn't sit well along the back of the cab and obviously there's nothing to attach it too anyway! Any ideas how to sort it out? All I got with it is the cover and a few metres of elastic.
Cheers for any help
Sam

Sorry I can't help but you might want to post in the hello/introduction post before the big nasties come and start laying into for not doing so first.

Hello and good luck by the way.....

Cheers,
Just posted in there! Completely forgot!! Thought I'd done it already but apparently not!!
