build sheet

iv got a 1972 chevelle ss and was wondering where to find the build sheet. its not under the rear seat and i havn't checked the front yet. any help?

Not all cars had the build sheet in them and after all these years even if it was under the back seat they are usually deteriorated. :2cents:

I have heard that above the gas tank is also a possibility but can't say for sure. Mine was under the rear seat but as stated above they aren't always there after all these years.
