Look at the air intake hose from the airbox to the throttle body. If there are two hoses all the way it's SD. If there is one with a sensor by the airbox it's MAF.

I think you have SD.

Oops, it a Lincoln!!

You only have one hose either way. See if it has a sensor in the hose.

Look for the MAF.
I believe all Marks used Speed Density.
