I finally got around to tearing my dash apart enough to get to my instrument cluster. So, I pulled out the main bulb I was after that illuminates the bottom half of my speedometer. Well, it appeared that the bulb was non-removeable from the base. Everything I can find lists it at one of 3 sylvania bulbs, none of which had the base to go into the instrument cluster. However, I dissected the bulb assembly I pulled out and it appears to be one of these normal bulbs with the legs bent out and soldered to the base. The base says PC168 and to replace entire assembly. I was able to make out 168 on the bulb also, which corresponds to a sylvania bulb. So, in the end, I want replace these bulbs with the brightest LED bulbs I can find. I like bright dashes and I NEVER want to have to tear back into the dash this far.... Thanks in advance.
