I am repairing my neighbours old Cannondale CADē (I think is it from the late 90's). The rear axle is bent and it damaged the freehub body's bearing race. I want to replace both parts. The axle is easy enough, (10x145mm QR). I have no luck finding the correct freehub body, have not even found a part number yet. There is no marking on the body, there are no markings on the hub.

Specifications:
Cannondale CADē
HG 8 speed cassette was installed
9 male splines on the body
9 female splines in the wheel hub
The bolt holding it together is opened using a 12mm hex wrench from the non-drive side (the female threads are in the freehub body).
Loose cup-and-cone style ball bearings with a 10mm quick release axle
The wheel is a branded as Rigida
On the NDS the cone bearing seal has "sachs" written on it.

Thanks for your help!

PS: I have some nice images, but I am new here and not yet allowed to attach images. It would make the search a lot easier.
