This was a little depressing

[abadsvt]

Well I ordered new rocker panels because i thought there might be a little bit of rust and wanted to take care of it. What i found was depressing. Tons and tons of rust. It actually ate through the front and rear part of the door jambs. I attached some pics. Do they make replacement parts for this? How hard are they going to be to install? Also the pick below with the green arrows is showing another problem that i found. There is the joint between the floor and the rockerpanel that has that lip. That is completely rusted through so there isn't any lip anymore plus as you can see the piece of galvinized piece of metal that someone replaced it years ago. Now there isn't much rust on the floor but all consitrated in the rocker panel and door jamb areas. Any tips or advice on replacing this would be very much appreciated. Thanks Josh

Here are the pics to help explain what i found. This is on both sides.
