I am using 5" for Tach & RPM, and 2 1/16 for the others....I will have it all cut out tomorrow night.
IF you go with 5", it doesnt leave much room on the left side of the dash for 2 gauges and an a/c vent as the dash is not symetric. I bought one a/c vent and ended up changing it out to get more room for spacing the gauges around. We will see what the final look is tomorrow and I wll post pictures of it..
Another step closer and very happy with how it is working out, still got to paint it yet (Matte Black)....Thanks to all those who contributed to the project and or I bought from
