The intake air temp sensors on the IAD are on the left on '70-2 models and <br>
on the right on '73s.<br>
<br>
'69 AT IADs had no temp sensor. That sensor stuck into the engine case and <br>
took the place of the front AAR stud.<br>

That would not be a '73 IAD. Must be a '72 or earlier. Only the '73 AT IAD <br>
has the TWO AT Vacuum Modulator ports. I don't know why.<br>
<br>
I probably have a correct '73 AT IAD. Let me know if you want me to check.<br>
<br>
'73 moved the Pressure Sensor port to the top. Oil VAPOR is still able to get <br>
there, but any LIQUID oil which has collected on the bottom of the IAD won't<br>
be able to get into the Pressure Sensor hose.<br>
<br>
Oil vapor still manages to get into the Pressure Sensors and condense <br>
there, but it doesn't seem to cause any problems. I used to clean those out <br>
regularly, but there was seldom very much, and removing it never made any <br>
difference.<br>
