I want to install Autometer Phntom gauges in my RS, and need to know the thread size of the oil gallery plug in the rear of the block below and to the left of the throttle body. I can't use the oil light sensor hole because I want to retain thr idiot light.

For anyone else who has aftermarket gauges installed in your RS, where did you put the sensors, and where did you get the adapters from?

What I would do would be to pull the oil sensor you have now, take it down to the hardware store, and get a brass fitting that is a "T" - male threaded into the block, and then two female threaded ends.

But as for answering your real question... I dunno!

For anyone else who's curious, i found a good thread on I-club that answers these questions.
