Here's the pics that I had time for yesterday. First is what I produced for the passenger's rear unibody hole, just coming out of my improvised "press":
And second, the best picture I could get of the installed driver's side mouseproofing. Again, I was working behind the rear window "pocket",...
Point is, it worked, and the trunk is mouseproofed.
In the engine bay, I was simply able to use standard vehicle body plugs that I had on hand. I'll still need to pull my plastic inner fender liners up front and check for the two body plugs that seabeelt told me about (on the steel fender channels). Otherwise, the car is mouseproofed.
I had to do this due to the need to store the car during the winter alongside my Superbeetle in my building that is about 800 ft from the house and surrounded by fields. The bug has never had a mouse in it, but it's been a chore keeping them out of the Spider! Hopefully, I'll not have that problem now.
I hope this post can help other folks with the same problem.
Todd.
