A.m everyone. I need to know the name of the part that's inside the housing after you take off the the slave cylinder. It has a rubber boot and a metal rod in it that pushes on the clutch fork. Just found mine was bent and has cracks in it.

 

Assuming from your screen name that this is with regard to the slave cylinder on an LT1/T56, the "clutch actuator pushrod" is an integral part of the slave cylinder, aka the clutch actuator cylinder. You would have to replace the entire slave.

 

Thanks injuneer. It's in stock gonna get it with dot 3 fluid.and go thru the bleeding process.hope I get it running today. And it is a t56 lt1 my friend used my name while I took it out. Thanks again
