Why Doesn't Enclosure Fit?

[bluntlunchbox]

Hey guys, I have a 2006 Sierra Extended cab and purchased an enclosure for under the back seats. The cut out on the box isn't wide enough but fits fine in my dads 00' Sierra 4x4. My floor seems to flare out towards the rear of the cab and so my box is useless!! Anyone else have this issue or am I getting jacked since my Sierra also has a sport bed instead of regular...dealer slipped that in there and I didn't notice till 2 days later after purchase

 

here's link to enclosure I bought on ebay:

I would doubt that the bed style has anything to do with how it fits (or doesn't fit in this case).

 

Could there possibly be some extra padding/insulation on your trucks floor?

I'll try to take some pics but my friends and family's earlier trucks don't have it...kinda strange.

i have the same problem

you ahve the 5' 8" bed yes?

so do i, uhm i read somewhere that its a hybrid floor of the 07s so the new extended cab boxes should work, but im not positive on that

im thinking about buying one of those boxes and cutting it and making it fit but idk
