Thread: slave cylinder question

I have a super7 with a sr20det and a Nissan transmission. My slave cylinder needs to be replace. This is were the challenge start, I have no idea what the transmission come out of (which I was under the impression that it was a 240sx). I have no model written on the bell housing or I can't find any number on it (unless I'm looking at the wrong place). So far I have order a 1990 240sx slave cylinder, it's about 3/8" to long (between the mounting location and the tip) but the right shape. Someone gave me one out of a D21 pickup truck, like wagner F103496, this one is a better fit however it's still a bit too long and it hit the bell housing.

The old one is a standard habco case, it's 3/4". What could I order to fit there.
