Different manufacturers' #74 bulbs will have the same bases but the envelope (the bulby part that hods the glowing filament) may vary a little. In some applications this makes no difference and in others it hurts.
So the question is, does the #74 fit and work?
If so, probly the thing to do is get a bunch of them (you may want to try eBay, import/export businesses post them there, yes they are "cheaper by the dozen) and replace all the dash lights at one time. (that way you won't have to tear into it again soon)
