Hot Rods 1930 Essex Instrument Bulbs

Have a 1930 Es*** Super Six dash panel and gauges.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
Does anyone know what type of Dash Bulbs I use?
I have the bulb sockets that fit the back of the panel, though the bulbs that fit in there are going to be too deep.<o></o>
Thanks!<o></o>

 

the hudson club has a online library. they might have a parts listing there. i know the i have a parts book for the stepdown hudsons, but none for earlier ones.
