Floor install

To do a complete floor pan you need bracing to hold everything square, A rotisserie is not the way to go! you need to make a jig to bolt the car to. A spot weld cutter is the best
it will only cut the pan material then you can use a air chisel to cut it out, As cracked said the pan is junk so you can cut everything out to the sub frame then it's easier to drill and chisel the welds, After the pan is welded i then put the car on a rotisserie for prep and paint work,Here's a pic of the way i do it on a jig.It's not a Mopar but ya get the idea!!
