L78 Oil Pressure switch reducers

[mbxlesney]

Bill...I have the 45 degree elbow. I did some more research and found that they used these (2) Reducer, Spacer or Connector on the U17 Gauge package cars also. And was used on the L35 and L34 cars also with a different 45 degree elbow. Another question I have is the aftermarket reproduced elbows do away with the use of these and are already reduced for the sending unit or manual oil line. Any info help would be greatly appreciated. Thanks
