Fisher Body plant code is the letter(s) under BODY No.  New entries highlighted.

Observations

• All 1955-57 station wagon bodies were produced at the Cleveland Fisher body plant (CL) and the bodies were shipped to Pontiac assembly plants around the nation.  Looks like we might add prior years to that range of years.  We don't know if the CL plant was used after 1957 for making station wagon bodies.  More data is needed.

• All 1957 Bonnevilles  (fuel injected convertibles) were built at Fisher Body & Pontiac assembly plants in Pontiac MI.  Documentation, including the 1960 and 1966 MPC, says body number is 2867SDX but cowl data tags show 2867SDTX.

• All 1956-57 convertible bodies (and possibly 58) were made in the Pontiac MI Fisher Body plant, most went on to the Pontiac assembly plant next door -- but a few bodies were shipped to Pontiac plants in other cities. 

• All 1955 convertible bodies were produced at Fisher Body plant with code L.

• We're not sure of the Fisher Body "L" plant location but suspect it was (is?) in Lansing, MI.  Bodies from the Fisher Body L plant were shipped to various Pontiac assembly plants across the nation.  It appears the "L" plant is another body plant (in addition to Cleveland) that doesn't have an adjoining Pontiac assembly plant.  So far, it looks like low production bodies (55 & earlier convertibles and early Catalina) were built there.  More data needed to draw any conclusions.

• We identified Fisher Body plant codes CL, P, and L that were not used in 1960 but were used in prior years.  We believe CL=Cleveland, and P=Pontiac MI and L=Lansing, see above.  More data is needed to discover other Fisher Body plant codes used prior to 1960.

• The Pontiac MI plant produced only Pontiacs.  Other Pontiac assembly plants were B-O-P (Buick, Olds, Pontiac) so production was shared with Buick and Olds.  Thus, more Pontiacs were produced at the Pontiac MI plant than any other plant.

There are more questions than answers.  More data is needed.
