Well, it may not seem like much in the next few pictures, but it sure was a lot of work. Let me start by saying that for a project like this, an air rivet gun made my life a LOT easier than it could would have been by hand!
I needed to make the ends of the chasis on the inside of the wells look close to original. Required some time and effort to be sure and the pictures really don't do well to show all of the work as the tires were in the way and the flash casts shadows, but it is what it is....
Front setup:
Back:
Added appropriate rivets down the side...A lot of work to make it look pretty ok.
Added Dzus fastener for the fuel cover (front body panel not latched so that's why the gaps don't look quite right...though I do still have a little work to do there):
