[...]I know for the trucks we use Série and then 10 or 20 normally if we cannot determine A, D, or C series (was there a 4th letter too)?
The
Série 20 was the only "Série" made and sold in Argentina. It's in fact a Brazilian name: it was made from 1995 until 1997 thanks to an agreement signed with
CIADEA, allowing GM to transfer the production from the Brazilian factory of São Caetano do Sul to the Argentinian plant of Córdoba

About the letters :
• D-20: Diesel engine;
• C-20: Gasoline engine.
There were apparently no
A-20 (alcohol engine) in Argentina
1,2. And
a Brazilian B-10 was promoted (pt), but it was
C-20 dedicated to export.
Former pickups from GM Argentina
were named C-10 (es), like the US models. For the record, GM stopped the production of all models from 1978 until 1995, the 1985-91
C-10 being made thanks to an agreement between
Sevel Argentina and General Motors for the production under license of the Chevrolet pickups

[...] by Gomselmash11; which to his credit was helpful [...]
Keeping in mind that Gomselmash11 was, to say the least, so proud of their country that they often "forgot" some details about other countries: they insisted, for example, that the
Série 20 was set as a 1995+ Argentinian product, even in Brazilian movies, although this truck line was made in Brazil from 1985 until 1995. So their assertions have to be checked before being used as source.
