Which bulb socket ?

[Motown 454]

Hi I've been trying to figure where to get a bulb socket to fit in these metal under dash courtesy light brackets.

Factory holds a 631 bulb, I tried using that to search. I tried by size of the hole it clips in. I guess I'm loosing my touch with being locked up here. Any help will be appreciated. LED or regular bulb. Can't just run to the Autozone to find a fit.
Thanks

It looks like napa#LS6542 would fit. Socket grounds through the bracket and has a single wire lead

Thank you!

You’re very welcome. Here is a link to the quick reference we used to use in case you might need other connectors. There’s alot more if the store has the old illustrated guide. https://www.napaechlin.com/media/2951/ne11211-illustrated-connect-guide.pdf
