S4 TII trans vs. S5 TII trans mechanical differences?
 

Okay, i am trying to figure out what the mechanical differences are between a s4 TII trans and an S5 TII trans. Everywhere I look it appears that the clutch fork and pivot ball as well as the slave cylinder are different parts #s. I am wondering if anyone knows if the pivot ball is longer on an S5 then an S4, and/or if the S5 clutch release arm has a different angle bend then the S4. The reason I ask is that I have a twin-disc clutch kit from japan and I am having issues the releasing, I have to adjust the master cylinder throw really far out in order to get the clutch to disengage and be able to put it in gear with it running. Any and all info is greatly appreciated. Thanks.

I had the same problem with the OS Giken twin disk. I had installed the first disk in backwards.
