ISO Wheel truck for DCC 70 ton diesel switcher.

[Ballard]

Need a wheel truck for the 70 ton diesel switcher, 2nd generation with 5 square holes in the gear box cover.  Oredered one from parts, got the 3 square hole version.  They have wrong picture in catalog.  This one uses the fatter, rounder worm.  I have sent back the newer truck, but the older one is sold out.  Of the 3 in the online parts list the last on has the wrong picture, it is the pic of a 5 square hole part, not the 3 square hole part. 

On mine, the little retaining clips, at the top which hold the truck, in are broken off.  That's what I need.  Appreciate any help you can give, other than buying a new chassis with motor.

Thanks
