Subject: Re: How hard is it to replace a slave cylinder on an 87' saab 900S?

I also looked at the picture. That looks quite a bit like what the item looks like from pictures i've seen. I know this was from a '78 Saab 99. My question is... Will I have to seperate the tranny from the engine to get at the clutch slave cylinder on the 900? If so, that makes my job appreciably harder. Thanks!
