Ok, I didn't find the correct bulbs for the map lights yet but I did find something better for the dome light and trunk light.
The dome and trunk according to Sylvania call for a 6411, which we found out can use a Polarg M-28 bulb (length of a 6418 bulb), but the tabs have to be bent to closer to grab the smaller bulb. Well the M-28 measure 1.5" long. The M-16 measures 1.25" and the M-88 measure 1.75". Since the M-28 is slightly too small, the M-88 will be the correct length for the dome and trunk light.
So instead of installing a smaller M-28 for the dome and trunk, I'm going with the M-88.
