Instrument Cluster Lamps

[gman]

Any ideas where to get a couple of the bulb holders that twist into the back of the Dash Instrument Cluster.....The ones that take the 194 bulbs......I'm missing 2 and I've checked locally with no luck. Not sure if any of the vendors here sell them or not. Hope I made this clear. Incredible what a few new bulbs do for the brightness of the dash. Now I can see how much over the speed limit I'm going at night. Also, was wondering why one of them on the back of my dash has a metal flange (for lack of a better term) protruding from it. Is this for a ground wire or something? Any help appreciated.
