The light over the fuel and oil pressure gauge has burned out. Do you have any idea what size the bulb is before I pull the cluster. That reminds me, what screws do I remove to pull the cluster?

Thanks

I think your car is a 124 body, if so the instrument cluster will come out without taking out any screws. You have to have a set of tools called “dash hooks” by most technicians. Any dealer should have the bulb in stock and be able to sell you the correct one over the counter.

Yes it is a body type 124. Where do I insert the "dash hooks"?
