Ok so i just got off the phone with the guy I bought the car from. Both of us are not i repeat not mopar data experts. Here is what we found out AX 68 3.54 dana. but he also confirmed as I did it is a 69 dana not 68. He remembers the radiator that is in the car was put in by a friend after the original one started leaking. He said his friend told him that he had one that should work but he had to modify it??? I think I need to have the body shop measure the opening in my car it may just have the wrong radiator in it. If thats the case I am a DUMB A$$... Thanks Larry J
