Tail Light Trim Mounting Question...HELP!

[SLS]

Heres my question(s) for the experts:


How many holes are drilled around the tail light opening for the clips that hold the trim on? And what size are the holes?

SLS has attached this image:




Are these holes even in the correct places????


As you can see, the bed I am replacing has 3 holes on one side...and 4 holes on the other. Also, a 3/8 drill bit is a hair to large to fit in these holes...but a 5/16 fits in them with a little bit of wiggle room to spare. This bed came to me this way (no clips or trim)...so I don't really know if it is correct to begin with.

The bed I recently bought has NO trim mounting holes, and I'll have to do a bit of straightening around one of the openings, but being that this truck is a Custom Deluxe I want to put the tail light trim back on it.

Any insight into this piece of my little puzzle would be appreciated!
