Oil pressure sender - What year/engine?

I would appreciate assistance identifying the year and engine this oil pressure sender is for. The numbers on the sender
60 6462849 016 0.

I believe it came off a 70 BB with guages.

 

That is the 60 lb sender for gauges. It originally came on the 71 and up, or may have been a late 70 model year switchover

 

Thank you
