1970 Chevelle Build Sheet Miscellaneous Information

Due to lack of sufficient quantities of build sheets from Arlington, Flint, and Van Nuys only Atlanta, Baltimore, & Kansas City are currently included in this effort. There is production information for Arlington, Flint, Van Nuys, and Oshawa but no specific build sheet information.

All U.S. 1970 assembly plants often used different wording for the same option. Additionally the unlabeled boxes were used for different purposes. Be sure to look at the correct plant for information. The information presented here ONLY applies to the 1970 model year, other years do differ. Be sure to pay attention to spacing, special characters (like *, =, #, etc.) and spelling in many cases. In particular the spelling of many RPO verbiage in box 107; they may differ greatly from plant to plant.

GM of Canada did not use the same paperwork on the assembly line as the U.S. so there are no "build sheets" as such found in a Canadian-built Chevelle. GM of Canada-built Chevelles are often found with what's commonly called a "Line Sequence Tag." This is further explained in the Oshawa, ON. section.

Data presented are applicable to SS396 and SS454 Chevelles only since documenting these cars is paramount to a buyer and seller. That's not to say that build sheets for non-SS Chevelles are any less important but there are just too many series, body styles, and options available to have information on all of them.

Some may fault this effort with the reasoning that it may be used by those producing fake build sheets in order to cheat and/or mislead a potential buyer with fake documentation. Others will applaud this effort so they can better defend themselves against those same unscrupulous individuals.

The intention of this material is to satisfy the latter of the two, the individual potentially buying a car and basing its heritage and value on such documentation as a build sheet. Hopefully, with the help of the information presented, you will be better equipped to combat potential fraud and save yourself some money. I will say that not EVERYTHING I know about build sheets are presented here, some information is just too volatile to release publicly. If you still have any questions on a build sheet, contact me though the Contact link at the bottom of each page.

Many do not consider the Monte Carlo to be a Chevelle. Consider though the Monte Carlo carries the same 13xxx designation as the Chevelle, the Monte Carlo was built along side the Chevelle (where Monte Carlos were built), and were sequenced in line with Chevelles. The above assembly line shows a Monte Carlo immediately followed by two other Chevelles. For purposes of this CD, and since the Z20 Monte Carlo SS was only available in 1970 and 1971, Monte Carlo SS information is not included.
