Ok, on the LT5 if the oil senders are bad; where would you hookup the test gauge?

Just remove the Oil Pressure Dash Gauge Sensor from the top of the Oil Filter Adapter and using whatever thread adapter you need for your test gauge with same thread as Oil Pressure Dash Gauge Sensor.
That will verify you actually have the correct oil pressure and your Oil Pump and Oil Pressure Regulating Valve are both working properly.
Now....it could (but rarely) be the Cluster (gauge) giving you erroneous oil pressure readings but I have never heard that happen before.
