I was given a marx 3/16th tinplate boxcar, the green GAEX 1950 one. However the former owner put lionel trucks on it and I want to restore it with the original trucks. He put them in with screws and secured them with nuts inside the car. My question is this, is there an easy way to get inside the car? I see a lot of tabs but not sure how to go about it without ruining it. Has anyone done anything similar?
Thanks in advance
