View Full Version : Pacesetter header plug

05-06-2008, 10:08 AM
I got a Pacesetter header off Ebay and it has a threaded hole in one of the tubes. It's a 3/4" hole with very fine threads. Any idea where I could find a bolt to fit?

Local hardware? I think that the biggest bolt used on a TR6 is 5/8" X 18, so I can't help you much.

Do you have and MSC or Grainger in your town?

EGR or a O2 sensor

EGR or a O2 sensor

If it is for an O2 sensor, then it's most likely M18x1.5.

One place I use for hardware is a company called Fastenall. I don't know if any are in Oregon though.

Did a 79 Spitfire have an O2 sensor?

Not factory, but someone may have had a bung welded to put an aftermarket kit in(like I did to my pacesetters when I had them coated).
