Hello there give him a call at 1-800-745-1680 and he will get you a set on the way. He is a very good guy with lots of good innovations and ideas and that leads to being very busy. I will look in my shop today and see if I still have a set for the smaller rotor....
No e-mail has come across my system from you about cover plates. It is possible that a spam filter got it if you used the yahoo.com address. The 1440 cover plate set is $170.00 plus UPS charges. They are in stock and will be sent to you open account. Please let me know when you would like a set. Thanks, M. Gorden
