93 Roadmaster.... that's a 5.7L engine, right? It should be attached to the intake with 2 bolts. Look for the thing that looks like a Chevy Smallblock EGR valve.
Also, if you're replacing the valve because you have an EGR code make sure you don't have a clogged passage in the intake acting like a bad valve.
