If I'm reading your psot correctly, you're talking about hooking up the rear O2s into the headers where the front ones need to go.
Either buy O2s, longer sensors, splice more wire or some rewire them so the ones in teh rear position do the job of the fronts.

Any time the o2 sensor moves down the car you either need extentions or have them turned off, especially if you do not use aftermarket CATs.

I use a Corvette o2 sensor from Bosch and worked great and IMO better then doing plug in extentions or hacking the harness.

you can swap the o2 sensors on the computer and use the rear hook ups. About 15 min of work and save 30 or 40 bucks. There is a post on here by Merv about it.
