Low Coupler Position Extension Piece Error

[Plow_Bender]

Hey Mr. Bach-Man,
I just received my large scale tar tanker today and I must say it's definitely a great model.  Since I run my Thomas stock with other large scale Bachmann products, I have to use the low coupler position extension to allow the models to be compatible with everything else I have.  Sadly when I opened up the packaging I found that there is an extra pair of the high coupler position pieces instead of the low ones.  That being said, I can't change out the couplers on my tar tanker.  Is there any way I can send back the coupler bag without having to send back the entire model?  The bag containing the coupler and position pieces is still sealed and hasn't been opened.  Any help would be very much appreciated.
