On my '73 there are a couple of different light bulbs for the dash. The light bar has an oblong light bulb, mine were marked only as C9S 1893. The remainder, inside the dash, is small round bulbs, marked GE 57 KM. Of course the replacements for those (that I picked up at a local O'Reilly's) are marked as 757 China(go figure) 4L. I don't have an overhead console, so I can't help you there.
On the new ones, I took the old to the store with me, matched up the bases and shapes to pick the replacements.
