480 distributor - date specific

[enio45]

Reason for my ask, my 69Z 9D car as ref above, has a 9A20 dated 480.

I've been told this is too early - it is a real 480 and was to believe it was orig to the car as all the other parts on the engine were. Having said that - you never know if and what.....at the legends judging - i got dinged for this, so if this is off the radar and not seen, im not going to fight the fight and go with what is accepted. Ill have to buy one and sell the one i have......trying to assess what others have seen on their cars and feel is appropriate.

Appreciate the thoughts and thank you Graeme for your input as well.
