För er som kanske inte förstod, så letar Henry i Estland efter två bakrutor (av de tre som denna hyttyp har) till sin Scania-Vabis AL36 från 1967.
Henry, I guess the cabin is the same on both Scania-Vabis L36, Scania-Vabis AL36 (which is the model that you have) as well as their successor Scania L50.
The model L36 (including AL36) is produced between 1965-1968.
The model L50 is produced between 1968-1974.
There are plenty of these trucks still around in Sweden.
From time to time trucks of those models are also scrapped, so parts should really not be too hard to find.
This truck (an L50) was standing nearby my neighbourhood a year ago.

I guess the truck was meant to be scrapped.
Even though it is a crew cab it seems that the back of the cabin is the same as on "normal" cabs.

I can check if the truck still exists. The owner is not easy to get in touch with since he is living a bit distant from the workshop, but I can try to find him and ask if he is willing to sell a few of the windows.
