I don't think a gauge will fit there so did you design an LED bar to install there?
Did you just cut out the Bezel?
Have any pictures to share?

I have no gauge, just an O2 sensor in a header collector. Instead, I used my voltmeter to track the sensor output. Very easy, very inexpensive and now I have a very tuned carb. So well tuned that I can't justify EFI now.

i got the gauge brettmc is talk'n about, riped it open and fixed it to the panal that the gauge's are mounted to right beside the temp gauge. then removed the seatbelt light lens, cut up the smoked lens that came with the gauge to fit in place. 
ok brett's talk'n about a dif. gauge. i used the summit gauge #sum-g2986 and the o2 sencer #sum-g2989
one more thing, i didnt cut anything up on the car to get it installed, so it's easy to undo what i did if i want it return it to stock.

Great.
Can you provide any pics of the rear of the bezel when you installed the gauge?
How did you determine the A/F range of the gauge?

no pic's, but not hard to do.
rip open the gauge, there's a ring the circuit board sit's on, use it. mount it next to the temp gauge. trim the edage so it sit's as far to the left as you can get it. used two-part epoxy to hold the ring in gauge panal and a little to hold the circuit board to the ring.
trim the lens to fit in place of seatbelt lens and hook up the wires and your done.
have'n installed the senser in my header collector yet.

when i got that gauge and was going to install it in place of my clock.
but after i removed the clock and cleaned and played with it a min. or two i got it to work! so i came up with this install.
been two mo. or so now and clock is running fine. dont keep good time
, but it's work'n!!

The innovate is the only way to go. Gives you real time data and you can put on a clip style sensor if you like.Go to thier website and read the info they supply.The Lm-1 is what I use and I would never go to full throttle without it on my engine.Very easy to run lean on my set-up until it is dialed in.

isn't a single wire 02 only useful with carb applications at idle and not WOT?
I have read that at WOT a single wire 02 usefulness is gone because you don't want to be at stoich (14.7:1 AFR) for the most power and you have to have a WB02?

Innovate just introduced a stand alone wide band O2 sensor with the processor built into the wire harness and a digital gauge for around $400. Check out their website and look under XD-1 (gauge) and LC-1 (lambda cable). www.innovatemotorsports.com

I recently just built one of the Techedge wideband O2 controllers. This is a pretty decent piece of hardware, it has 3 analog voltage inputs and 3 thermocouple inputs. It will drive a display they have available or you can connect it to a PC. I currently use it for a class at school, and I have to say it works real well. It uses the LSU sensor, which only cost $35.

Ok I don't want to high jack this thread but can somebody give me some detail on how an O2 sensor helps in tuning the car? How and where does it mount? What would be the purpose of an inside the car guage?

Inside the wideband sensor is a regular narrowband element. The pump cell has the ability to "offset" the NB. So instead of switching hi/low at 14.7:1 (lambda 1.0), the pump cell can make it switch either at a higher or lower lambda. The amount of offset is controlled by how much current you feed into the pump cell.
The controller monitors the NB element and adjusts the pump cell current to make the NB element switch back and forth. The controller than looks at how much pump cell current it has to supply and calculates what lambda that represents.
In addition, a WB sensor has a fairly narrow heat range it works in so the controller also monitors and adjusts the heater element.
