18t and 20t clutches........WTF
 

I'm getting a new clutch tomorrow, but my friend that ordered it for me said there are 2 different numbers in the book. One is called a 18t and the other is a 20t. What is the difference between these two and will they both run fine with my 13b and GTU trans?

Re: 18t and 20t clutches........WTF
 

Difference is the number of splines on the input shaft. IIRC, the TII trans has the 20 spline input shaft, and the NA trans has 18 splines.

N/A is 22-spline, T2 is 23-spline.

I got no idea what the 18/20t means....

It's an N/A
 

So which one is it- 18 splines or 22? I'mnot going to et a chance to look @ my trans till late tomorrow, but for furthr reference i would be nice to know. and to make sure I get the right clutch.

It's 225mm, 22-spline, 15/16" input shaft.

T2 is 240mm, 23-spline, 1" input shaft.
