Chilton'* manual #28200, page 1-11 has them all listed. This book is usually on the shelf at any auto parts store. It covers the Bonneville/Eighty Eight/ LeSabre for 1986-1999. That'* the best source I know of.
I'm not familiar with any GM source, but if that'* not good enough for them, let them wallow in ignorance
Your car is listed as (93, Vin 1, SC):
There is some possible erroneous data on this page, but 93 is accurate. For instance, the 95 and 95 Vin 1 are PROBABLY inaccurate. It lists the 95 as being the same specs as the Series 2 which didn't appear until the following year for Vin 1.
