back seat frame demensions wanted for early cj5

I would love to know who makes back seat frames for the early cj5s. I cant seem to find one anywhere and I need one to complete my jeep. I have the mounting tabs on the floor but for some reason the back seat got lost 40 years ago. If anyone has any information on who makes these, I would like to know.

 

No one makes just the frames, but Bestop does make fold and tumble rear seats.

 

i need the mount, I bought the bestop one and I have the 60/40 which I will have reupolstered to match the rear but I would like some dimensions for me to make a mount or know of someone that would make one.

Hope this helps, because i'm not sure if I understood your question.

 

I think I just found them, they are listed as 55-83 quick rear seat disconnect. Does this look right?
