Original RC Big hauler parts

[USAF_Andy]

Mr Bach-Man,
I have an old original Big Hauler set, the RC one that I believe was the first that y'all brought out.  For whatever reason, my dad decided to remove the trucks from the cars and tender before shipping it out to me from California.  Unfortunately, it is looking like he has lost the screws that attached the couplers to the cars.  I looked in your online parts catalog, and they appeared to not be availible there.  I currently have a tender and gondola that I would need screws for.  The set originally had the ten wheeler (still have), a gondola (still have), a flat car (who knows where it ended up) and the four wheel bobber caboose.  I never saw these mentioned again, everything else seems to be powered off the rails.  Out of curiosity, why did y'all decide to go that route originally?  Thanks in advance.

Dear Andrew,
The service department will be able to provide screws.
Track power, or more sophisticated battery RC, were viewed as the way to go.
Happy Holidays!
