Hey guys. When I ordered my new luk clutch kit from Carolina Clutch, they did not have a slave cylinder in stock. I priced one today at the stealership and they said there was an update kit out for the slave cylinder that included a clutch interlock switck and an upgrade tube, totaling in at $220.00. Has anyone else heard of this, the truck is a early 99 with the original clutch and slave cylinder and a 6-speed. Thanks!
