Title: 77 Suburban Color Mystery
Post by: Ghazi67 on June 03, 2025, 11:48:02 am

Hello
Hope everyone is OK

I am trying to help a friend w/his 1977 GMC Suburban project. 
I need your help in identifying the original truck color/s from its build sheet.

Appreciate any details or helpful links
Cheers
