There's different "grain of wheat lamps" and what you want is the 14 volt variety.
Look on Ebay and get a bag of 100 for short money. These bulbs thread into little
twist lock holders in all of the dash switches and all you need is a good pair of
small sidecutters. (What you DONT want is the 12 Volt version since they will
go away too fast)

The shift bulb is another story, maybe you could solder in a grain of wheat lamp
or try LEDs being aware that you have to have polarity correct.

You can get LED replacements for your car, some are huge improvements with better
light and less drain on the alternator, with a much longer life. Some of the offerings are better than others, but generally LEDs make the OEM bulbs obsolete. More info on request.
