trunk rust question, how much do i cut out? Options

[i love porsche]

ok, in the rear trunk, at the rear most, behind the dogbone, its pretty decently rusted....now the rear panel isnt rusted, just the trunk floor...my question is can i get by with just cutting out the floor, or do i have to do the whole back section like sir andy..

im not the greatest welder, so id like to stay away from the entire thing, if possible, i dont really wanna compromise the strength of teh chassis

i dont have a pic of the spot, so i will graciously use one of sir andy's (i hope you dont mind)

There is a lip on the trunk floor that comes up the rear panel by a little less than an inch. The trunk floor and rear panel are spot welded together along this lip. If you sand the paint/rust down a but you will be able to see each sport weld which you can then drill out with a very handy spot weld cutter.

You only have to remove the trunk floor.

If you check out a website of any of the resellers, there are pictures of the replacement floor panel. Once you see the panel you will get a better idea of what you will have to cut out.
