I realize I am bumping an old thread, but I thought my content added something, was relevant to this post, and would be more organized than creating a new one.
I recently obtained an SF2, overall in great shape minus. One issue was that the car was cracked and super glued back together. I bought a new die-cast car that matched the back glass a little closer and looked much better. I used tin snips to remove part of the back of the vehicle to replicate the shape of the original and modify some of the innards for the post to run through. Also drilled through the dash of it for the bracket. Reassembled with car superglue and some hot glue to reinforce a few things on the inside of the car. The post/bracket are secured with the screws strongly as they should be. You can't tell the vehicle isn't 'full' from the top view.
By somewhat replicating the original shape, the car is able to have the full range of motion and you don't have to modify the optics or lose functionality. It works great, looks great, and is more fun because the added weigh requires several more hits to 'win' car crash, instead of the initial 3 full hits my machine had.
This was a pretty easy and fun project, I would recommend it to anyone interested.

Backglass to reference. Not a perfect match, but not bad.
