1st off. its 95-100 dgress out right now....
so I'm cooling off a bit,
got all the "stuff" out of the way, you may not need to remove all of this but I'm installing a 9in, and fuel cell, fuel lines, adj uppers, along with new motor and trans ,
any how, hears some pics of tha area to be worked on.
I suggest you install the inner support first, so the frame still has strength when you cut away the outer side,
heres some pics of my fun today
