O yeah, i know its the O2 sensor because i jumped to diag. connector, and the only code I had was for an O2 sensor fault.... Plus the guy who owned this car before me, prob. just hacked off the damn plug.... cuz i cant find nothing.

If it's a daily drive a 350 swap is not economical plus a lot of work to say the least. Do you have a O2 bung hole in the headers? If not you will need to weld one in. If it was my car I would go back to the manifold exhaust, go to the wrecking yard and look at the motor that still has the O2 sensor in place, pick up the stock manifold. That should give you a idea of where to look put in a new sensor and you should be good.
