1970 Challenger dash pad fasteners

[jamesroney]

There are about a dozen 10-24 threaded studs attached to my dash pad.

Can anyone tell me what kind of nuts were used?  Did they use the threaded hex nut with an integrated washer, or did they use a stamped steel speed nut?

I know that I need 12 of them, and I know that they are 3/8 heads...but I don't know what they look like.

Thanks!

Pretty sure it's a speed nut.  I'll try to get a pic for you.

Floyd is correct.
