Isn't the 60 votes thing is more a reaction to the Gringich stated policy of obstruction before cooperation style politics - before that Democrats and GOP crossed party lines more often to pass legislation and did not vote in lock step, I definitely recall Reagan/Tip O'Neill worked together across party lines to pass legislation most recently. Also, because of the 1980's Byrd Rule that requires 60 votes on avoiding the filibuster in the Senate on bills that affect the budget in certain ways after reconciliation - it sometimes lets bills only need 50 like the GOP was trying for with their ACA rollback last session.

Now it seems rare, the Maginsky Act sanctions and the Iraq War powers are the only consensus votes that come to mind.
