Ok im putting together my B18a1 and B16 cable transmission. heres what i have after a ton more of google time. I need any B16 half shaft.. The difference is. Hydro B16 = Male half shaft. Cable B16 = Female half shaft. Im also seeing a lot of people saying to use the 94-97 Integra LS or GSR half shaft but i havent seen any proof of this working. With a B18a1 Engine and Cable B16 Transmission a 90-93 Integra LS half shaft WILL NOT fit.
