73-91 Suburban Question

Does anyone know if the rear bench on the suburbans, mainly 79 burban, need to be removed to lay frame?

pugz on here burban rear bench isnt in the stock place and it almost lays body

yeah it think it does i didnt notch my frame and im no where near frame but when i raise my burb up it looks like it needs super swampers but its a tow pig it looks lowered when its air out

my 3rd row had to be removed. it could be put back put you would be in the roof. it sits in the very back facing rearward
