Gauge Cover/Bezel nut driver size? What is it?

[Trailltrader61]

Evening- I have a 1988 C1500 and I want to replace the instrument cluster gauge's light bulbs- I got the main cover off, only to find there's 4 tiny nut driver bolts- does anyone have a clue to what size of nut driver I need for these?

Thank You- Trailltrader

7mm I think should be able to get em with a 1/4" drive socket and extension.

7 mm for sure just pulled one out of my truck the other day.

Thank You- I couldn't figure it out (Of course my precision tools only went to 6MM!!) so I got angry and ordered from Northern Tool a 1/4th drive, SAE & Metric from 4mm on up. I was going to order just what was needed but then I'm like "Eh, I'm going to see this in the future so I'd better make it happen"
