3911068 spring w/dampner
10214034 O-ring type seal
460483 Int seal
24503856 keepers
10125896 bushing
25163463 fuel pump

I would think those part numbers are still available BUT I'd let your vendor confirm and if you had any questions regarding replacing part #'s just post back. I'm assuming the GM source there is properly affiliated.

I saw that post the other day and didn't pay attention to it. I use some reference materials that have been with me for years and I always start there and reference from the "oldest original" service part and do the replacing numbers from there. There's certainly some great information there.

My reference material is old enough that I can generally ID what might be considered NOS for most applications.
