I am currently in the middle of this same project. Here are some pointers.

to understand how the car is put together you must first remove the fenders, rocker trim, door seals/thresholds, paint, lead filler and undercoating. At this point you will see a few things. There is a seam that makes up the seal channel. There will be hundreds of spots welds along this seam. They must all be drilled out. Next on the lower section of the outer rocker you will find another seam. Again more spotwelds to be drilled. The ends are a little different.

The front of the rocker fits nicely around the door hinge post. Try to mimick this unless the hinge post is rusted out(likely) The rear edge the rocker makes a sandwich. the layers (from outside to inside) are the rear quarter panel, outer rocker, inner fender support, inner fender. If you are careful with your cuts you can slide the new rocker between the quarter panel and the inner fender support. Getting in there to weld is a different story.

I ended up trimming the end of the new panel and tying it into the joint. I good weld will make it nice and sold here.

Once you have the outer rocker out you can follow the seams for the inner rocker. I did not have to do any work on my car here. The inner panel you may want to consider butt welding a patch piece depending on conditions.

When done coat everything with a liberal coating of POR15(or equivilent). Prime, paint. Your done.

Good luck,

Jamie
