I'm also looking for a lot of info about the DTM kadett.. (I see that a lot of photos from my photobucket are linked over here
..)
The car at Opel (nr 43) can't be one of the later cars, because those had polyester hood and front bumpers...
I also have one photo, where you can see the original gear stick in the car. And not the sequential stick.. So what that means? I do not know.
original kadett gear stick/knob:
sequential stick:
I do know there is a maintenance shop at russelsheim, where they work at older opels, but what exactly they do, i don't know.

Ps.
This is also a very nice photo (think it is the DTM engine, but not sure) :
