I need your help.
Over the weekend I started assembling a MAZ KTKZ-537L.
The main groups (cargo compartment, fuel tanks, chassis, cab and winch compartment) are already defined.

I intend to start detailing the groups and then to unite all the chassis. For reference I am using some images from the site PRIMEPORTAL, and a publication of Tankograd.
Unfortunately these my two sources do not detail the engine compartment, my idea is to try to fill the engine compartment, with a set built in SCRATCH, I already have the dimensions of the D12A-525 engine, fitted to the truck.
Do any of you could tell me where I find pictures, drawings or anything that could lead me in the construction of the engine compartment and interior. Another option would be to make the radiators to try to shrink the gap.
Can not stand this emptiness, agree.

Thanks to all who somehow can help me...
