They are made by EZ-WIRING. I am looking at removing the factory gauges. Leaving the original housing and installing either an sutometer speedo and tach, or a dolphin speedo and a dolphin quad (volt,temp,fuel,oil) in a second housing.
Let me know what your guys opinions are. I know some members like factory, but I want something different. I am keeping the original and using a second housing.
I can't remember who makes it, but some company already makes what your looking for. Stock housing with speedo/ tach and quad on other side. but not cheap. there was a thread on this a while back. web-site links and all.
