Replacing all fluid nipples on a 13B

[Ender]

Many of the oil and coolant nipples on my motor parts are in poor condition, mostly rusty, yet the rest of the parts are in great shape. If anyone has replaced them by tapping a thread and screwing in a fitting I would like to hear which pipe taps and fittings are needed. I would gladly take the time to do it myself, but I no longer have lots of time to finish this rebuild nor do I have readily available transportation to run around looking for pipe taps and fittings. However, I will do what I can in the absence of input.
