I'm trying to buy a "Decked" drawer system. To those of you who know about them, they fit pretty tight in the bed of your truck, with little wiggle room.
I have a 1990 1500 6.5' bed, and when shopping for my drawers, I find they stop supporting anything older than 1999. I can't find anything specific online, so I need to know if anyone is aware of any bed changes between '99, and '90.
Talking to Decked themselves, they just cautioned me about buying for a system outside of their specified years. Talking to GMC they said essentially, "see if someone has a '99 and can compare measurements with you."
