Tub measurments?

[langester]

I looked for a while but couldn't find what I was looking for. Anybody got the measurements on the inside rear tub? I need the measurement from the inside of the top of the rear tub at the tailgate and right before the striker posts from passenger side to drivers side? Thanks in advance.

I've got 56 3/8 for both.
