Wait! Stop!
Make sure by the year of rack you have. Early racks use all SAE fittings, and AFIAK, later racks use all metric!
It is a common misconception that SAE racks use metric and SAE, but it's wrong. It does work, but it galls the threads. The pressure side is 9/16-18 thread, and the return thread is 5/8-18. We manufacturer our own fittings to solve this problem.Matt Jones

OK Matt, now you've got me a little worried since this is what I received from AME when I asked:
The non-metric racks (like what you have) have a 5/8" thread on the return, and 14mm on the pressure side. Both are o-ring sealed.
I bought my fitting kit from AME last September. Would it have been correct at that time? I've seen no leaks but haven't put any miles on the car, just running in the shop.
