Ive got a '77.  do you mean the narrow piece across the back?  not sure what it was for but it was definately too small for anything like a fifth wheel support.  i took mine out.  i thought it was a support for the spare tire.  may not be the same piece you are referring to.

Take a picture and post it.
There shouldn't be anything above the axle from the factory.  Is it riveted on or welded?

looks bolted in, someone said it was a brace someone put in for a fifth wheel

but its right above the rear axle and it goes right across the top of the frame

My 85 has one. It looks like a thick steel plate with a hole in the middle. In the bed there's just a hole and inside the hole there are threads for a ball. I'm not sure how it's installed because I never looked closely at it. I would remove it if it is bolted in.

My 4x4 has one, a steel plate that a goose neck ball is attached to.
