Did either of you read pjc360's post above. Three B-W Vreg failures in 3 months, changed to Wells and no problems since. So to answer the question, "yes, some are better".
BTW, 64X2 was out of luck on the bulkhead. Both 63 & 65 cars had dedicated "bus lugs" for the large ammeter current, so no melted bulkheads in those years.
