Grizz, it sounds like you found the problem. If I were you, I would just make a shim for the module and you should be good to go. Use a piece of rubber like Barry suggested, or even a piece of bicycle tire inner tube. It should be quite easy to do. Me, I don't like paying guys to do things that I can do myself. Give it a try, and let us know how you make out. You certainly won't hurt anything.
