Is the old bulb still in there? What's written on it? According to standard parts information, a 194 bulb goes into the bracket for the striker in the dash. I know for sure it's a wedge bulb if you have A/C on that 88. The 194 is GM p/n 9421330. Or you could do an aftermarket LED equivalent.
For a tad brighter, you could use a 168 bulb. GM p/n 9425542. Or LED equivalent, if you wish.
The only other bulbs it lists for glovebox is the metal base twist/lock deals, 1891 and 1895.
