proline put the wrong body in the right bag when I bought my slash body. Called up tower (not their fault, prolines fault) and they said, "oh, well, that's not our fault, but we'll send you the right body right away!", which pleased me greatly.
Just recently they sent me the wrong color A-arm, called them up, they told me to keep it, and the right one was on the way.
If you explain your situation you might be able to get the cans from them, but that's kind of your fault, I always check out stuff that I get in the mail right away to make sure it's what I ordered. :)

Good luck, and......get some pictures in here when you get home! ;)
