Yeah, something is wrong with the old big block one. That's not important at this time, though. I did get the small block DC distributor back together this morning, but won't be putting it in until Monday (gonna go work on my son's Dart installing the clutch hydraulic master cylinder this afternoon). Always something to do.

And, no the roll pin isn't the issue with the big block dist. It's in correctly, the reluctor is just loose. I'll address that on a different day.
