    Default 1990 bed drain holes ?

    guys,
    i have a bed liner in my 1990 k-1500 truck, along with a plastic tool box. all was there when i bought the truck 3 years ago.
    last night i parked with the front downhill and it rained and filled the bed up with water.
    i opened my tool box today and drilled drain holes in the bedliner, but laid under the truck and didnt see any drain holes at the front of the bed.
    are there any or will i have to drill my own ?
    thanks much

    You will have to drain your own.

    There is a small hole but the issue is GM usually sealed it up from the factory with the sealant in the corners. SO just get a decent sized bit and knock tow in the bed. Ive had to do it on every truck ive owned from years 1980 to 2008.. Apparently they dont think that a sealed box will hold water and rust

    ok guys, i laid under the truck with my drill and actually found the factory drain holes. but as murdog has explained, they were clogged with sealant. i have them cleaned out and it now drains.
    thanks again guys
