You are probably seeing a generic photo. So far as I know, all mopars have the starter ring gear on the converter.
Older LA engines used a 4 "star" shaped flexplate. Aftermarket flexplates can be had to adapt a neutral balance converter to an externally balanced engine.
Realize that there are "several" external balance situations. A 5.9 Magnum is externally balanced, but not the same balance condition as an LA 360
