Oxygen sensor nut , electrical connectors
 

Does anybody know where to get the nut welded into the exhaust for the oxy sensor.

I also need a three wire water proof PLUG of the oxy,
does anyone make a universal one.

Also does anyone know were to get the washers for motor mounts.

these are very difficult items to get

Check Autozone/Napa/local parts store. They should be able to supply generic 3 wire O2 sensor with nut to be welded to exhaust manifold. It is typically recommended to install within 18" of the cylinder head. I think with the 3 wire O2 sensors there is a little more flexiblity, though.

Any decent muffler shop has the O2 sensor bungs, and can weld them in for around $20 or so.

Try B&b exhaust, they make an extension cable for the o2 sensor and they have the bung for the sensor..... Pat
