Chevrolet Silverado 1500 Forum : “2008 silverado bed will fit ”

I think yo should just find a bed to match the 2004 cab. That's the reasonable way to do it.

i think the chances of it fitting right on arent worth it for the extra effort it would take to match the 04 bed that you know will fit

although the bed may fit,  the body lines wont match due to the change in body styles, and the tail lights will be different which may or may not be interchangeable, so like the other post have said, just find a 03-06 bed

03 - 07 classic bed.

99-06 and 07 classics all had the same bed...the only difference between a 99-02 and an 03-06 or 07 classic is the front end...
