Opel Blitz 4x4

[Trbocharg]

Hello everyone,
At work I am creating a 3d model of a 4x4 WWII German Opel Blitz and I need to figure out what the steering setup was. I have included some of the reference pictures I am using to create model. This model is going to be used on a next gen video game and I want it to be as accurate as possible. Also what would the transfer case look like and is it correctly placed in the side blue print?
Please help, any pictures or info would be highly appreciated.(Especially Pictures)

I found a gallery that you might be interested in:

There are 37 different high-resolution pictures (01.jpg through 37.jpg), though none are close-ups of the steering.

Thanks Mambeu I've been using those for the past few days...But I think thats a 2wd model and again no steering.
But thanks again anyways.
