Install new style couplings in old Mantua
I want to install new couplings on my old Mantua yard steam engine, I took it apart to see if new couplings will just fit in place but they don't.
Are there kits to go from the old ring coupling to the new ones? if so where do I get them. My engine is about a 1957 vintage, I know this because it was my Christmas present, tried to kill it when I was a kid but the darn thing still works.
