Where's EGR valve on '87 350 TPI

Trying to locate the EGR valve on my 1987 IROC, 350 TPI Motor.
My service and overhaul manual doesn't tell me where it's at.
Is it down behind or beside the distributor cap? Or under the intake somewhere?
I just got done driving the car, it's bogging bad, and checked the code which shows EGR.
How big of a job to change it?
Thanks

Not hard to change. You need to pull the plenum to access it. I'm pretty sure they are discontinued though.

Thanks Bob. I just called CarQuest and they can get me one from their warehouse for tomorrow.
I am in Eastern Canada.
So I will need new plenum gaskets then?

Yeah, get the gaskets. Get the FelPro set if you can.
