Ive got a brand new Sunpro A/F ratio gauge for sale. Its not an expensive gauge (paid 30-35 for it), but its accurate. Ive watched it next to my scanner and its on the money. I am replacing it with another style gauge which matches my other gauges better. I bought it about 3-4 weeks ago. I painted it flat black (the bezel and the bracket). I didnt like the chrome. 15 bucks plus shipping.
