I have a couple of Walthers / Life-Like E8's and want to convert them to Micro Trains couplers. They will be run in A-B-B configuration so only the rear coupler is a concern because the front looks OK and will couple to the train even if its a tiny bit high. I am not sure what Micro Trains couplers to get for the rear of these units. I did e-mail Micro Trains a couple of weeks ago but no reply. That rear coupler has me stumped as for what could even fit. Radius's on our track are quite generous so no tight curves to worry about.
