So you're standing at the parts counter.....

Sorry, didnt mean to come across as an ***. While I agree sometimes with parts people, they can only use what is given to them. Knowledge is power and the corporations dont give them(for the most part) power.
What I was trying to say(in fewer words lol) was that it is sometimes hard to decipher the correct info to help ourselves.
I'm a fairly "stock" guy, but for people that have swapped drum to disc, sbp to bbp. FMJ spindles etc etc.
For me as mentioned it was the elec ign(which entails a few parts).
I compared 73 dart vs 84 Ram...different coils lol.
My bad….
What I meant to say is 1970 vs 1973 ignitions will have some differences. Points vs electronics. Ballast resistors are different. Chrysler started electronics in 72.
As for the clerk at Advance or Autozone, I order everything online. I’m just there to pick up my order.
