Digital gauges

[redhot]

Hi,

Going to install some gauges in my car during the summer. The best option I have found so far by thinking, is to install digital gagues behind the dash-grill on the left side of speedo. Keeping the stock apperance when not using the car and having the option of turning them on/off.
Also considering just having them on a small pod underneath the dashbord, but hoping it can be done behind the grille.

1) Does there exist a combination gauge with oil temp & pressure? In digital
2) Any opinions on the setup?
