I have a Weider Fitness gym 9940. The right arm (as you are seated) of the upper butterfly press has begun to get a stress tear in the metal near the upper cable attachment part. I've checked on-line and have been unable to find a replacement arm. It's part number 11 in the parts diagram. Does anyone have a recommendation of where I can buy the replacement arm for this fitness gym?

Thanks for the assistance.
