Manual Transmission - Master and Slave Cylinder

Do I have to install a new master and slave cylinder in a 99TA if I go to a LS6 Clutch Kit? I have 50K miles on the car and would like to just keep the old ones if possible.

LMK if they need changed to go to the LS6 Clutch Kit...

TIA

The master and slave where upgraded for the '01-'02 cars and it would be better to change yours out to the '01-'02 since you are going to have the tranny out. Your hydrolics will go out eventually and you would have to do it anyways, this will just save you time. I would recommend upgrading.

Yep highly recommended replace the hydraulics, along with doing the drill mod.
