I need to replace my Campagnolo Record rear hub, 1984 vintage. I have everything but the hub shell itself in good shape. I'm wondering if the shell from an earlier Campy hub (Record, Tipo or Gran Sport) made for 120 mm dropout spacing would work acceptably to rebuild the wheel as it was, with 126 mm spacing.
In other words, did all the hubs have pretty much the same flange spacing, relative to wheel centerline, and distance from drive-side flange to freewheel seat? That would mean that the only difference was in spacer and locknut widths. For reference, the flanges on my broken hub are 57 mm center-to-center, and the freewheel seat is 7mm off the drive-side flange center.
