Hey David.
I do see your order of the Roadmaster baseplate part # RM-523160-5 and the etrailer SD Non-Binding Tow Bar for Roadmaster Direct-Connect Base Plates part # e74ZR. Those two parts will have no issue connecting to one another out the box. If you do ever need replacement base plate tabs (Roadmaster calls them arms) you would want to order part # RM-ARMS. On the product page you will need to click on installation details and fill out the bracket order form prior to ordering.
It's easier if you fill out the form and then give us a call to place the order and let the rep know you already filled out the form.
Or are you needing the tow bar to also connect to a Blue Ox baseplate?
