73 Correct Master Cylinder Broadcast Code Label

[Jimmy P.]

I was wondering what the correct MC Bail handle broadcast code label for my non power brake 73 L48 should be. The JG manual says YA for non power brake cars. However, when I talked with paragon before ordering one they said that YA ended with the 72 cars and the 73 used YC. So, I purchased the YC. Now, I'm second guessing myself. It's only $3.00, should I go by "what's in the judging manual?" Clarification please!
Thank you!
