hey, New here. I havn't got alot of knowledge on panel beating just know more of the mechanical side of things. Just needed to know where to cut and the easiest way todo so.
So here we have the left side of the rear quarter.


 
now the right side.


 
and here we have a rust free panel (have two of them)

Just try to cut out all the rusty areas and leave a bit of a border of solid metal around them.  Then trace around the old rusty stuff on your new panel, cut out the shape and weld it in.  It would probably pay to squirt a fair bit of rust converter around the place after you cut the panels out too.

It may be easier to build everything around the panel on the floor! 
 
You have a lot of rust cutting to do.
 
Good luck
 
Matt

cheers for the ideas hope it all goes fine.
