I just cut one of these off to delete the EGR on my build.
I didn't want to fight the rusty nut off. I have the tube, cut flush with the nut at the manifold if somehow that will help you. If I remember correctly, the 94-95 tube has one vac (?) line coming off of it, where the later ones have 2. I put 97 manifolds in my 94 and just plugged the 2nd one off.
