Sorry I just re-read what I typed. Guess I had 8 3/4 on the brain and meant to type 7 1/4 not 8 1/4. Thanks for correcting that for the OP guys.

My car came with a 7 1/4 but now has a 8 3/4 from a 66 Formula S I found in a JY many years ago after damaging a replacement 7 1/4 in a gas pedal stomping "SHOW OFF" incident.
