So you are saying you could not just use any 194 bulb behind the guages?

problem is i cant find a base..
The instrument cluster uses a variation of the wedge bulb. They are mounted in a twist lock base that plugs directly into the printed circuit board on the back of the cluster. When sold with the base, these are called PCxxx bulbs, for example a PC194 is basically a 194 bulb that comes soldered into a PC (Printed Circuit) board twist lock base. Older GM cars (around '90 and earlier) used a standard bulb which would plug into a separately available twist lock base, allowing you to easily change the bulb since you could re-use the base. The newer ones have the bulb permanently soldered into the base, so when one burns out you have to try and find the special PCxxx version rather than just replace the bulb in the existing base.
if you are going to change your instrument cluster bulbs to brighter ones, I suggest you just get the separate PC wedge bulb base, then you can use any one of the non-PC standard T3 1/4 wedge base bulbs by just plugging them in.
