Bachmann... which coupler shank size do I use?

[hoboblues75]

I have the USRA 0-6-0 Switcher & Tender (NY Central).  I want to convert the tender to the new magnetic coupler.  What shank size do I need?  Do I need any other parts?  It currently has a rapido style coupler.

or the dummy coupler shank size if the new magnetic couplers don't work.

anyone?

Bueller?

Dear Hobo,
I'd start with the medium shank, and adjust from there.
Have fun!
