This answer is in the Oil Cooler Repair section.
The Oil Cooler Repair Nipples are actually the same Nipples that screw into the Filter Housing.
The Oil Filter Housing is tapped for M18x1.5 threads (but my knowledge is only related to 617.952).
If this seems familiar it is that same size as the spark plug holes on some older cars.
Last year Sears was selling this sized tap for around $13 (Made by Vermont America). They are less on eBay if you find a seller that has a decent shipping price.
I have pulled some used ones off Oil Filter Housings at the Junk Yard to verify that they are the same as the described Repair Nipples.
