A friend asked me to swap out the trucks on a set of Weaver scale sized aluminum passenger cars. He had already obtained the trucks.
I removed the first truck, and discovered that the trucks he purchased do not match the originals.
Below are pictures of the old (left) and new (right) trucks.
The old trucks have a mounting stud and a raised bolster.
The new trucks do not have the mounting stud, and the bolster is flat.
Did my friend obtain the wrong trucks, or is there some sort of adaptor available to mount these new trucks to my friend's cars?
