I have seen many tutorials on converting from latch to knuckle couplers on American Flyer cars. What I am looking for is info on replacing latch couplers that have broken; specifically how to set the pin. Is there a tool that's needed or do you just use a product like J-B Weld to secure it to the truck. My efforts so far have only resulted in a broken coupler so any info will be much appreciated.
