I would say 4hrs?? my computer is being dumb it wont let me look it up to see how long it should take sorry. It does but does not display time or anything! Maybe you can check, Cortez, CO, zip is 81321.
i would hate for you to come and not fit though. it was on a 85 xtra cab if that helps/stock bed.
It has cracks right on the sides of the bedliner almost at the end too, and it had deep cracks where the bolts go in.
let me know thanks.
