Does anyone know the difference between EGR part numbers:
Delco 17110813
and
Delco 17085897
I really want to find an original for my 87GT but both are listed. Based on Blooz info. from his EGR post, his vehicle had 17085897 but in my last EGR post, TK found 17110813 is listed in the P22 book for both Manual and Automatic. Rockauto lists them both under the same application.
