$100? That was a bargain for how clean the part came out. If you have gone this far, you might want to look into the rocker panels to see if there is rust inside. That $2000 for the whole car might start to look pretty inexpensive.
I am also enjoying the thread watching one of my cars twins being put back on the road. Watching all of these cars being restored has me wanting to make a rotisserie now and doing my GTV up right and not half baked when it comes to the body prep.
Are you going with a glue in or rubber gasket windsheild?
