thanks consistseeker
when i prepared next parts for the assembling it turned out that a lot of parts are missing:
72b -the inner side of of driver compartment sidewall (a big one)
82b - the bottom side of middle mudguard (also a big one)
74k, 74l, 74m - those are parts of big hatch from rear (on second picture)
a minute of silence...
got myself together and continued the project
eventually, no matter how i tried, the color of the printed part, of the side of driver compartment, didn't match (part 72b that missing)
so i found the spare color at the end of the journal and made the parts from it
also i assembled the floor
as i wrote, parts 74k, 74m, 74l are missing too
as usual, i cut those from spare color
i am starting to get used to it and its no god
when i tried to insert front floor to its place, the fuel tank got in the way, so for future assembling - glue it after you put the floor in the place
