It sucks Armond.
We have the pleasure of a one year, one number only distributor.
Any other number and it is not for your car. I found one with the same numbers except the middle three were close.
Close but no cigar. It was for a 74 one year only automatic.
I don't know anything about using others and rigging or whatever some are doing to make it work but you need a dizzy with the numbers 74 Tii 231 180 013
