The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Source for tell-tale bulb sockets for '66 GMC?

I've been searching for these and can't seem to locate the right item. The closest I came was a local O'Reilly autoparts store, but the ones they had were just a little too small.

I assume you are talking about the instrument panel lights (oil light, temp light, etc).
Try these guys.

It is who I used and I was happy with their products.

Thanks, yes, that is what I am referring to, but I didn't see what I am looking for on their site.

Here's a pic of what I need (the whole thing, not just the bulb):

You're in AZ. Go to DVAP and get some originals from the junkyard. Should be cheap enough.

You got me on that one.
I know the GMC's have some differences from the Chevy's and this may be another one of them.
I did my whole dash on my 64 and never came across anything that looked like that.
Looks more like one of the lights from a 67-72 dash.

How's this?

That looks pretty good, thanks a bunch! Would hate to drop the $20 on a set of them if they don't fit, but it looks pretty good. I don't think I've been to rockauto before, I bookmarked it.

I haven't made it up to DVAP yet, but have been meaning to go to look for a rear bumper and some other parts. Truck is out for paint right now... once I get it back I'll get my parts list together and maybe make the hour trip up there.

The GMC dash cluster is a circuit board, of sorts. The bulbs are housed in a socket, that turns into the back, to secure it and complete the lighting circuit...different than the Chevy dash light sockets of the same year.
