Drain Holes In Bed of a Short Fleet

[magwakeenercew2jh]

Both of my Short Fleets came with spray-in bed liners over steel floors.

I'm putting in a home-made wood bed.

I'm wondering if there are any stock drain holes in the bed that might have been sprayed over when they put the liner in.

Even though it will be covered up almost all the time, I'm going to puncture the liner where the drains are supposed to be for a "just in case".
