Its believable to me that M-20 could now just be the designation code for a 4sp. I was just told that M-20 stood for muncie and made sense to me because of the M. What does Saginaw mean? Where Its made?
Correct me if I'm wrong, muncies were built in Muncie, Indiana. Saginaws were built in Saginaw, Michigan.
Fantastic purchase. I love the options.

Welcome to the site aj. As you have already discovered, there are lots of nice folks here. You have a cool looking wagon there. Do you have any interior photos, especially of the shifter area? GM usually installed the shifter on the factory manual transmission cars pretty far forward, and on the left side of the transmission tunnel. Its almost under the ash tray area, below the radio. That allowed them to offer the manual transmission on vehicles with both bench and bucket seats, without any shifter clearance issues with bench seat cars. I have a factory built 1980 Malibu 2 door V8/4 speed car. I'll post a photo or 2 here that shows the shifter on my car.
As for not having cranks for the rear door glass, that's normal. All of the '78-'88 A/G body 4 door sedans and wagons have fixed glass in the rear doors. On the wagons from '78 up, and on the sedans from 1981 & up, the rear doors have the swing out vent windows at the rear, behind the fixed glass. The hot ticket is if you have a car that has factory power operated vent windows.
As for verifying that its a factory built car, without a build sheet, it could be tough. If it was originally titled and sold in the States, then I'm not aware of any services offered for Chevrolet owners that could help you. If you could trace the ownership of the car back to the original owner, then maybe there will be some paperwork there that could help you. Bit of a long shot though.
Keep us up to date with the progress on your car.

You could try this link if you have a VIN. Provides quite a bit of info: https://www.dmv.org/vehicle-history/vin-decoder.php
I have a 79 GP and the build sheet says m20 for the manual transmission. Yes it's a factory 4 speed car
My 79 Grand Am 4 speed cars have a MM4 designation. Not on a build sheet, but on the window sticker (from the PHS)
They are all Saginaw.
Pictures may be of some use. Lever on the column, tach filter on the firewall, etc...
Cool car either way....
