Quaife has one part number that covers the del Sol VTEC, all non-VTEC Integras, the '92-'93 GSR and the '99-'00 Civic Si; and another part number for the '94-'01 Integra GSR and '97-'01 ITR.

That would lead me to believe that you can take an LSD from a hydro B16 trans and put it in a cable B16 trans, but an LSD from a hydro B18C trans would not work. Just a guess.
