so who knows how to install them. there is a how-to for 02-03... is that the same thing??? Can someone point me in the direction of a how-to maybe?

 

and will the 02-03 gauges fit an 01? they have the extra hole but will they fit otherwise?

 

yes it will work but there is a bit of fitment issue
i got the 01 reverse from procarparts.com and i think they did the measurements base on the 02 cluster .. cause it was a bit off so i had to improvise and make it fit.. it turned out pretty good..

 

this one is a single piece of plastic and isnt the individual gauges. it also has an extra hole on the tach. does that stuff make a difference?
