Looking for bulbs for 69 Barracuda hood mounted turn signal assemblies.

I believe those are the ones that go in like a pistol cartridge. I don't remember the number. 312? 327?

These are what they look like, but 327 are 28V

EDIT May be no. 330

Did you look in your service manual? There are fuse and bulb charts right before the start of the wiring diagrams, section 8
