There are typically two types of slave cylinders - external to the bell housing and internal to the bell housing. You need to get under the car and see if you can determine what you have. For the external slave you should typically see a small cylinder bolted to the rear of the engine with a rod extending back to a fork sticking out from the driver side of the bell housing. The internal type slave will not have a fork - there will be a hydraulic line extending into the bell housing. The internal slave is cylindrical and fits over the transmission input shaft. Hope that you have the external type as the transmission has to come out to replace the internal type slave.

I would try to determine who your existing master and slave cylinder are made by and their piston size or model number. The safest thing is to replace them in kind since the cylinder dia (size) will have already been figured out by the manufacturer.

And as a lesson learned (from someone who really shouldn't have had to learn it) the slave cylinder needs to be rotated in it's mount to where the bleeder valve is at the top (high point). Otherwise you will get the air out of the system.
