Maybe I'm misinterpreting something in the discussion and posted starter photos, but this is the DB Electrical PMGR starter PN#3223 I installed in my Pantera a couple of years ago...no issues.
Well, there was one issue. The flange on the DB starter is thicker than the old stock starter. So, I installed longer studs in the bellhousing to ensure I had plenty of threads for the washers and nuts to secure it.
