HO coupler with spring 40' rolling stock - Part number

[PatBarr]

I need to order more couplers.  I want the standard ones that come on 40 ' stock with the springs.

What part # do I order?

They are "EZ Mate Mark II" couplers.  The link shows the model number from the on line store (medium, center shank).
