I have done them about 3 to 4" back from the collector. Make sure you try to put it as close to the 12 o'clock position. You do not want moisture getting on it. If you put below 3 and 9 o'clock there is a possiblity of moisture getting on the sensor and that could ruin it.

Ok thanks But I was looking where the 02 sensor is and its laying on its side on the manifold and I dont think there is enough wire to run the O2 sensor to end of the full lenght hedder this is a 1988 Dodge 4x4 with a 318 btw
