Was the armoured car robbery that happen in the movie Heat really happen?

There was a armoured car that was robbed in NYC over 40 yrs ago. It happen at a new shopping center that had just opened. The truck drove up to a loading dock and collected money from their stores and the banks that were there.

When they got back to the loading dock they were robbed.they got away clean.

Now the armoured truck waits on the street and not on the,loading dock ramp.
