Where can I find the series numbers for my Cadillacs?

[J.C.]

I'm trying to update my member profile before the August 10th deadline.  Can anyone tell me where I might find the series numbers for my 1979 Coupe DeVille and my 1991 Coupe DeVille?  Any insight would be greatly appreciated!  Thanks!

The 1979 Coupe Deville series number is : 6CD47

and for the 1991 Coupe Deville it is just CD47.

All series numbers are listed in the CLC International Membership Directory.
