are there any differences between the b-series transmissions other than gear ratios. will and b-series clutch fit all engines?

 

There's also differences between a cable b-series or a hydraulic b-series. Would like to know about the clutches part also though.

 

so i called act clutches today because i bought a HSD015S clutch disc which it says is for b18c and b16a from del sols and 99-00 civic si, but it didnt fit. when i called act i told them i have a 1st gen jdm b16a with a y1 tranny and they told me i need a HSD807S clutch disc which they sell for a 90-91 intergra so do some research before buying a clutch

 

LSD options differ as well.
