956 / 962 differences....

[SpeedsterMS]

Hi everybody,

I'm making a 3D CAD design (solidworks) of the 962....(spaceframe tube, it's easier)

the aim is to build my own car...(I know it's a lot of work)

I own some books on this car (upietz, morgan)

on one of these there is a blueprint of the monocoque (956).
it would be the basis of my design.

but i want to build a 962 (in fact D.smith in canada will provide me the bodywork)

I know that the 956 tube is close to the 962 tube.
to meet IMSA regulation, the front axle has been moved 14cm (5,5") forward to keep the feet behind the front axle.

my problem is when I compare detailed pictures of the tubes i can't find where the 14cm have been added.....
(even the wishbone seems to be very close)

If somebody has the answer......(I think, he would be as nut as am I )
