70 roadrunner alternator question

[sidewalksurfer]

Might be in the wrong section. Did the early 70 roadrunners run the 69 style or did they all get the revised 70-71 style? I have a 69 and 71. I just got to know which one to rebuild

All 1970 models originally used the, new for 1970, "Isolated Field" alternator with the "round back" style end shield and with two isolated field connections along with the electronic voltage regulator. The two field connection "round back" style was used through 1971.
