Martye, thanks for the reply. Your second picture is what I'm struggling with but my car is different than yours. Here's a pic:
But seeing the trucks dangling in your first pic gave me the solution! My trucks are attached to a mounting plate that are held onto the white plastic frame with 2 screws. By removing the screws I was able to lift my trucks high enough to clear the bottom of the body shell and the plastic frame, which has the interior glued to it, slid right out. Here are some pics:
Thanks again! John
