I think I found what you're looking for..at amazon...

but the larger issue, to me...is that the repair shop needs to pay for this...or get busy and find yours. I used to do the books and inventory for a repair shop...and parts like that don't get tossed out..usually just misplaced. The squeaky wheel gets the grease...go down there and "squeak" till you leave with your foot pedal or cash. If you make a fuss, they will make you whole one way or another. Donna
