Porsche 959 / 961.....
a friend of mine own an original 961 chassis !!!!
in fact this is the same used for paris/dakar and le mans

the one he own is a former lada/poch (metge)...
part number are 961 000 .....
the only 961 chassis has been crashed in le mans in 1987, then the car has never been rebuild.
my friend, has contacted Porsche Motorsport in Stuttgart to begin a rebuild, but porsche want only one thing : buy the chassis, they never help him....
so he is waiting ....
