I've got an autometer Z-series narrowband Air/Fuel guage that I've taken out of my car after about 6 months of use because I went to wideband. The wires are snipped a bit short, but just splice new ones on and it will be fine. Other than that it's pretty much like new. The first rennlist member to PM me can have it for $25 + S&H, that's less than half the new price.

 

You've got PM
