my os giken twin plate arrived and doesnt look like its going to work with my box, i run a si cable box out of a b-series 90 ls integra in my 89 crx. the problem i have is it seems that the clutch hub offset seem 5mm to far out towards the gearbox- hitting the end of the gearbox input shaft( and only using 5mm off spline on number 1 clutch plate. OS say they only make 1 twin plate cable clutch for the b-series honda and its to suit EF8 and EF9. could the input shaft be differant on the ls box??

 

99% all B series are the same ... ALTHOUGH 90-91 LS are completely different than all the rest. The 92-93 cable trans. are the same internally as all the 94+ hydro's. That includes the vtecs ect. The difference in then 90-91's is that the main shaft is much smaller in diameter than the newer ones. Also inside is 100% different from the shift forks down to the bearings.

My guess is find out what year LS it is for and go from there.

And if the shaft is tight against the clutch already than it is the right one and then just try flipping the discs to make it work. Sometimes they dont come together correctly out of the box.
