Thanks for the info Ol Grump.
D8Pete,
The D2 winch is constructed almost exactly ths same as the D2n, except all parts are more heavy duty on the d2n and the D2n weighs about #250 more, meaning all the parts are in the same places and appear similar but most will not interchange. the two winches will bolt up the same to any d2.
Here is a link to the instructions for the D2n,

The instructions have the mounting and modification instructions for the different D2s, there is a fair amount of fender modifications needed, along with the seat risers.
I would recomend going through the winch and replacing all seals and any bearings that are needed, they are prone to self distruction if not in proper condition, and the parts are very hard to find.
