Hi Jose
If you are worried about this sort of detail, then the old Italeri kit has some other issues you might want to know about too. The fuel tanks in the kit for the rear area are way too wide. Look at built kits on line and check out the gap between them, then look at the gap in your reference pics.... the spare MG magazines affixed to the rear will give you perspective.
The front seat and fuel tank (driver's side) are moulded together, etc.
Detail is quite chunky and thick, etc.
Then there is the tyre and tread shown in the pic....
and yes the vehicle was conveniently backed up for the lovely staged pic... check out the tyre groove depression in front of the tyres!
If you are interested, if you wade through the numerous pics on this website, you will find pics of SAS jeeps showing just how varied they actually were:
