I have a 94' GS300. I really don't like the stock gauges (tach, speedo, etc etc) inside, is there anyway to change or replace them with anything? Thanks!

 

slap an APEXi Rev-Speed meter in front of the speedo, and slap a huge APEXi Tach in front of your stock tach That'll be a dope combo to do.

Or replace the whole thing with a Stack multi-meter but that'll run you a few thousand
