@ MidMazar: you are right about the susp! so...
I have shorten the suspension cause it was way to high and glue it on the differentials. The front suspension on the one side is pressed cause in the diorama, the "Sam" will have stepped on an obstacle (rock or tree...)
Here in the procedure of measuring and center the 2 systems...
And on the Sam...
Then i made the transmission system with the center diff from parts of two donor kits and the actual one...
I still have to build the basis for all the diffs..
Thats for now...Thank you for your time!!
