The FH-7700 uses a DS cone that is different from most Shimano hubs. It extends inward further past the bearings than most, (don't know if this serves a purpose), and is most similar to the XTR FH-M960/5.
Also, the rubber seal ring is different from prior Shimano FHs. These seal rings were different on each side (DS/NDS) and matches to the seal interface on the freehub body. The closest match for the 7700 would be the cones & seal on the other FH from the same era or slightly after. Possible candidates would be 6500, 6600, 5500, 5600 & 4400, and possibly a few others. You need to pull the tech doc and compare the part numbers for the seal ring.
Here is the tech doc for the FH-6500, that uses the same rubber seal ring. See #8 & 9.
Not sure if the more modern FHs that uses the one piece cone/seal ring/cover is the same size as the prior ones. Here is an example. See #5.
