Micro Trains 1133 (med shank) or 1134 (long shank) will retrofit into the bachmann/rapido truck mounted draft boxes. The reason one would want the long shank over the medium is for really tight turns to increase distance between cars so they don't bind on each other or there is a lot of overhang on the ends past the draft boxes but I don't think you have any cars like that right?
The ends of that car don't appear to overhang the draft boxes on the truck though so you should be ok with 1133 assuming none of the cars bind on each other through the turns.
Check out the instructions for the kit on the micro trains site here (click on the pictures). That way before you buy you know exactly what it will take to swap those.
I was havin a gander at that a little earlier, I think I can manage this. heh. If I fail at one, I'll send em in.
they ended up having 1134! Wondering what "burnish" the parts means tho in Step 1. Ended up having to run back out for graphite lubricant :0
