OK, I have a bad oil pressure switch in my '88 GT. I have the special deep socket to unscrew it. But, I recall I need to get a crowfoot to go on the square brass block at the end of the tube that the oil pressure switch screws into.
I recall starting to twist the tube the last time I changed it and that I really needed crowfoot socket the next time I changed it......BUT.....I can't recall the right size!
I want to buy the crowsfoot on the way home, but I don't know what size to pick up......Can someone PLEASE, OH Please tell which size I need?
