Help with speedo removal

For my 48 connie - my speedo is not functioning - cable is intact as the odometer advances. I have contacted Bob''s speedo in MI for repair - any pointers on how to remove the speedo from the dash panel - looks like very close quarters and could use any tips anyone might have.

Thank You!

there are 2-3 clips around the inside edge of the rim that secure it into place. These aren't too bad to get to with a 3" extension on a ratchet. IIRC, it's a 3/8" nut. The bulbs are all press-in, and will come out with a slight lateral push. If they're a bit stuck in and are worried about breaking them, the wires for each are short & lead to a butt connector about 6" back. I had the most difficultly getting it freed from the drive cable, but it's a lot easier once it's hanging out of the dash

Thank you sir!

hope it helps. I've spent more than a few hours underneath a dash, dodging crap falling in my eyes.
