You know, thats what I think too, or was it 86???? I have seen 85 year blocks drilled for the rollers. Tried and true rule of thumb for these mid 80's rigs seems to be the rule that nobody knows for sure.

Have you really? Then, I would say 85 was the first year cause they didn't do extra machinin just to waste money. You can bet on that.
