I have a Marx 6" hopper with 4 wheels mounted through the sides of the frame and non-operating plastic knuckle couplers.
I's like to convert it to a pair of 4 wheel trucks with tipping couplers so I can run it with my 3/16 cars that came with my 999 set.
1. Is it practical?
2. How is it done?
3. Where do I find the parts?
Thanks in advance for any help you can give me.
Tom
