i seem to remember bulb numbers of 1157 maybe 1180. these bulbs are the same except that the bases have different locating pins. one had 2 pins 180 degrees apart on the same level. the other had 2 pins but one was higher than the other. (i am not 100% sure on the 1180 #) but the 1157 should be good. go to a good parts store and they should be able to identify what number you need.
40 years ago my father drove truck and he would bring home all the different bulbs you could imagine. somehow i remember i remember this because because i was working on my 33' plymouth and my 66 belvedere.
but a good part guy should be able to look in his lamp book and figure out what you need.
