Is there a way to determine the SLP SS # from a VIN #? I bought a wrecked 1996 SS that I cant find the SLP sequence number on anywhere.

 

No. The SLP build number was assigned by SLP, and is not "matched" to the VIN.
If you join http://www.camarossoa.org/ you can get this info. and a signed "Letter Of Authenticity" from SLP.
Have you tried to find the previous owner. They may already have this stuff.
Also visit http://www.chirpthird.com/ubbcgi/ultimatebb.cgi for all kinds of info. on SS's.
