Default PCV valve on a 91 GT?

Probably a stupid question, but my car is idling rough. The Haynes manual says it may be due to a clogged PCV, but I can't find it. Do the fox bodies have a PCV? If so, where is it?

Have fun with that change
And don't forget to change the crankcase brether filter underneath it (pull the PCV, pull the grommet it sits in, reach in the hole and you'll feel it).
It is a pain to get out if the intake is still on but should be done if your PCV is ready. There is a fancy little tool to hook into the wire mesh casing, but a corkscrew worked for me with the intake off
