Just acquired my 71 Cutlass Supreme Convertible. Going to be replacing dash bezel and lenses. I figure "while I am there", I should go ahead and upgrade bulbs to LED's. done this on my other restorations and it is by far one of the best improvements that can be made. Currently do not have an owners manual to tell me what type, and how many of each type of bulb I need. I would like to go ahead and order the leds before I tear open the dash to minimize downtime. Can someone shoot me a copy of the owners manual page with the bulb listing or tell me what I need to order? Car has rally pack gauges if that makes a difference. Any help would be appreciated

There are a total of 11 #194 bulbs in the gauge cluster, speedo, & tach. You can also use the #194 bulbs in all 4 side marker lights but the light does not diffuse like an incandescent bulb. I restore the instruments in the dash & offer a LED bulb option when I do them. I don't have the other bulb numberss in front of me right now.

So nothing other than 194's back there?

194s in the Clusters. They also used 194 in the housings above the HVAC controls and above the wiper controls if you have the courtesy light package, IE glove box light, trunk light, underhood light, mirror map light, Etc... then you will have four bulbs in the housings. Otherwise just one of those. If you do have the courtesy light package there are several other bulbs throughout the car.

Thank you!!!

the back courtesy lights in a convertible near the side armrests are the 90 bulbs.
