So I'm looking to replace all the gauges in my 2002 baja 29 outlaw. Where is the best place to shop at. I want gauges I can just plug in to my current wiring.

Uhmmm...unless you have newer livorsi's nothing is going to just "plug in", though the process of replacing gauges is usually pretty straight foreward, single or twins?? standard or monster? Greatlakes skipper on ebay usually has some decent gaffrig set deals (fuel,oil pressure, volt, temp, trim tach and gps speedo with antenna all monster sized for around 700

Twins, and stock.

If your looking for new, We sell Livorsi, Auto Meter and Teleflex. http://www.diamondperformanceparts.com/home.php

I bought my entire setup from Bill at Diamond Performance, he was outstanding to work with.

Who do I need to get in contact with to have a Livorsi oil temp gauge rebuilt? Or easier to just buy a new one & have the colored bezel on it changed?

+1 for Diamond Performance

Bought several things from Bill at Diamond performance, always excellent price service shipping etc. He is one of the good guys!
