Hello and welcome to the forum
Sorry to hear about your bad experience. The parts can be found as Jeff has pointed out, but it will take a little leg work if you are going to hunt for them yourself. As to places in AZ, neither of the following two handle what you need but might be able to steer you in the right direction. It can't hurt to call or email them;
