Here's my contribution to the idea bag...
I used Autometer Cobalt Speedo, Autometer digital tach w/shift light, and ProSport Oil P, Water T, and Volts digital gages. Sticking to the blue/white theme as my car is B5 with white vinyl top... white interior.. Also incorporated the BlueToof microphone for the Alpine Head unit...
Fuel Level and Trans Temp mounted under dash also Autometer Cobalts..
I kept ALL of the stock pieces for keeping/storage as well and bought these dash plastic parts on eBay. My original stuff was way too nice to modify and if I ever sell they can go with the car....
