I've been mocking up the new ar5 on my junk 4.8. I've gone through and measured about 7 different slave cylinders from solstice, corvette, camaro, and finally a mustang gt. The Ford slave pictured here will in fact bolt in and release the ls3 clutch. The only downside is Ford decided to forgo the bleeder valve?!? Wtf? So I'm not entirely certain I want it. The reason I'm researching slave cylinders is to eliminate the 3/4" stack of washers behind my Colorado slave...
