Now obsolete
That EGR is offically obsolete. Delco can supply an "All Makes" EGR valve, but it is basically a Standard Motor Products universal fit valve, and I have serious doubts about whether it will work properly in our TR application..
As a Delco dealer I may be able to find the correct valve somewhere in the Delco warehouse network, give us a call in the shop. Monday's a holiday for us, but we'll be around after the 4th. (888) 727-8748
