If the question is about my unibody the floor is pretty rough. Someone covered it with a sheet of aluminum years ago.

 

ouch, they do not make replacement panels for the Unibody beds. I thought about using a later bed panel or finding a Unibody that was going to the wrecker as a doner.

 

A later bed floor could probably be made to work. For me where I live if its going for scrap its in the same condition or worse. I'm really not worried about the floor in mine. I had about 1000lbs in it the other day it took it fine and it'll never be a show truck. My next one I'm actually going to build a wood center for like the flare sides of the day.

 

My Unibody mutt truck. Been sitting for a few hoping to get back on the road this spring/summer. Everything is setting on a 73 LTD Police car with 460 PI and C6 trans. Nothing stock here.

 

here's mine a 72 medium box uni-body just something different

.

 

Did you blend the box yourself?
