I think it must have been from an S10 or Ranger, it's pretty small.
Also rides nicely on the rails of my 4x8 trailer.

Sorry for the delay...
Top 55x20.5
Inside bed rails 47
Total deep 15
Let me know if these measurements make sense to you.
It's a Contico Tough Box
Locks are broken maybe, but I'm sure with a little creative hardware use you can fab something up

They make sense. Let me measure up my rig later today. I'll get back to ya. Thanks
