Not sure if it will work or not, but might be worth a try if you don't receive the high knuckle coupler from the seller. I replaced the dummy knuckle coupler on the front with a USA Trains knuckle coupler and it was at the right height to couple up to my 1:20.3 rolling stock, plus it coupled reliably to the Bachmann couplers and the Accucraft couplers. I just had to clip off the tab at the end and enlarge the hole on the coupler shank to get it to fit. They are fairly inexpensive at roughly $9 for a package of 2.
