It just depends on the reason it doesn't fit. They may take it back if the pad is the wrong one. The fact that you've used an underpad might have kept the new one clean enough. Glad you have a good shop to go to. It makes all the difference when you want custom fitting done.
bumping my post test.
I saw your test post for awhile but now it is gone:). This thing is really screwed up.
