IMHO this #2 post is the correct answer.
Post 12 backs it up
Stuff I posted is referencing a 69.
To finish the 69 story this is the cap that was on the dist pictured above.
No "R" as you can see.
The thread I linked started as a question about the originality of some parts that were removed to get car running after its long nap.
As you can see the cap was dismissed as replaced.
I bought the "R" one as it was supposed to be"correct".
Then conflicting info shows up later.
The no "R" cap is on car but we have the 'R" one [minus overspray" on the shelf.
Always looking for more clarity on stuff including this.
Pic 1 is the "R" cap we bought for it.
Pic 2 is the no "R" cap that was on dist.
Pic 3 is the coil that came with car
Pic 4 is date and purple ID paint on dist that came with car.
