The original Ford specification (below) was for a standard round o-ring and flat backup washer. Both are industry standard off the shelf items - SAE -330 o-ring and backup washer.
McMaster will sell you a bag of fifty 90 durometer buna-n -330 o-rings for $12 and a bag of fifty 90 durometer buna-n -330 backup rings for $9. That works out to $.42 per set. Wanna guess what CNH charges for the 2 they put in a bag???
