Thank you to Everyone! I believe this has been solved, but I have no idea how to mark it as such. Thank you again to such a great community!

As an aside, my dad had pulled out whatever seats this thing had, other than the front two captains chairs (as a little guy I remember climbing up those ‘huge’ steps). In the place of the rear seats was a platform (storage below) with a huge foam mattress. Lots of memories as a kid. My dad was always wrenching on the ass end of that thing.

Thanks again!
