Rear:
Large-globe single-filament lamps (backup, t'signal, `73-up brake) are 1073 or 1156
The small-globe ones (`73-up taillamp) are 67 or 97

Front:
Large-globe dual-filament (t'signal/parking lamp) are 1034 or 1157
Small-base sidemarker lamps can be 1893, 1816....or the round-globe 57

Alternate choices typically have slightly different voltage and/or current ratings, or different expected life.
