Guys, I'm new here so thanks for letting me join your group.
I was asking specifically about the size of the Torx and what size wrench was needed to remove the box. I found another thread and answered my own question.
But just to be sure; T-55 torx and no other wrenches. Correct?
Thanks again

 

yes, t-55 for the bed bolts, try to loosen all 6 first, it is not uncommon for 1 or more to be very very rusted and tight, try to get some PB blaster or other thread lube in/on them and then wait to the next day to try again.

You also need to loosen and remove filler neck, 3 screws/bolts

And unplug tail lights/license lights
