Help identififying a 6-36729 Animated Caboose part number

Anyone happen to know the correct Lionel part number for the little red arm that the conductor stands on for the animated Lionel Lines Caboose? I accidentally broke one of the pins bending it back straight.

There is no Lionel parts diagram that I can find on the site, but I have managed to identify some contenders based on the short description:

  1. Part Number: 630-2729-217
    LINK BAR MLD RED/ANIMATED CBS
    Price: $ 0.50

  2. Part Number: 630-6729-218
    COVER SLIDE BAR/ANIMATED CBS
    Price: $ 0.90

  3. Part Number: 630-6729-219
    SLIDE BAR/ANIMATED CBS
    Price: $ 0.85

I’m thinking it’s the last one, but I want to be sure. I’m probably not the first guy that needs this arm replaced so the conductor’s lantern will light up again. It was working before I broke the pin off.

I also sent a note off to Lionel hoping they can help me identify the correct part number I need, but I thought I would also ask here.

Thanks.
