Which coil?
So I stopped at my local parts store and asked for an ignition coil for my 68 360. He didn't look it up and judged asked "One with an internal resistor or one with me resistor?" I didn't recall seeing any kind of resistor under the hood so I got one with internal resistor. Now I'm thinking hey what about that so called pink resistor behind the dash? Did I get the wrong one?

Ya figured as much. I went back and got a Standard UC12 universal coil with NO internal resistor. It's stamped right on the side "use with external resistor".

Uni, why are you replacing your coil? What are your symptoms?
If you have a coil in place and if you have access to a voltmeter, check the voltage to ground from the high side of the coil. If you have points make sure they are closed. If you read 7-8 volts you have an external resistor; if you read battery voltage you do not.
Coils rarely fail, are often replaced.
If you put in a coil that requires an external resistor and you have none something will soon burn up.
There is a huge body of literature on this site on this topic. Do a search and you will find what you need.

Just replacing stuff. Timing set, water pump, fuel pump, gaskets, painting things blue! Getting a new distributor too (stock) so figured I may as well replace the old coil.

If ya got the extra money it's cheap insurance go for it.
It's like some guys run tires until they go flat before replacing it..
As a friend of mind call's them "May Pops". I said hell that's dangerous
doing that.
He says yea but, I get my moneys worth out of the tires..
I told him dang let me check your tires before, I ride with you on the freeway..
I told him hell that's the crap well did as teenagers when we were short of money
yeah he said and. I still do it..
So to head off waiting for things to go bad~~ replace them before they fail and chances are you won't get stuck out on the road..
