Anthony P sharing knowledge with those who care to listen Joined Jan 24, 2007 May 22, 2023 #3 John, my 87 (extended production) has code PZ rear springs. GM part # 477512. pic of tag attached. didn't find any more cross ref to GM 477512. crash book for part #'s notes to see end of section 7 for spring codes....don't have those pages. other than OE rear springs were constant rate, seems most folks choosing Moog 5379 for replacements. likely it's Moog in the ACD box.
