I just acquired a set of Lionel passenger cars set 6-29046. I would like to try my luck at putting some people in the seats. The directions say to remove the two screws and the roof will come off. There must be more to it than that. There appears to be two catch clips on each side centered over the windows. Squeezing the side of the car does not help.
Any advise would be greatly appreciated,
Thanks, Doug B.
