Anyone replace their stock oil guage with a mechanical unit?
My oil pressure switch is broke and figured it would be good to
switch over to mechanical one. If so, where can I buy the kit?

Thanks,
Andrew

 

Nobody? What I really want to do is plug the hole where the oil switch
screws in. I broke the switch when installing the longtubes and now oil
is leaking from there. Anyone know what size threaded bolt I can use?

Thanks,
Andrew

 

You broke the oil pressure sending unit? How did you do that installing headers? Are you sure you're not talking about the coolant temp sensor?

 

Broke mine the other day taking out a spark plug

 

You've got a 93 so the sending unit is above the oil filter where it's actually reading pressure before it hits the motor. If I were you, I would actually plug that port and use the port behind the intake so you get your reading from the motor. You can hook up a mechanical gauge to either port or just buy another sending unit from any local autoparts store.
