>> The slave cylinder mounting can be a high failure item. From the factory the nuts were all metal prevailing torque locknuts. I use P.C. 10.9 hardware, bolts up from the bottom with hardened washers under the head and the locknut directly onto the cylinder base. The rear bolt can be tightened with the assembly in your hand. The front one needs to be tightened with the bracket in place that goes down the side of the gearbox. It is also important to have that bolt in the bell housing secure to keep the main bracket from flexing.

>>> For that lever you really want to prep it to be an easy fit on and off the shaft. Anti Seize! Especially on a Syncro when the cylinder needs to be serviced it is so much easier if you pull the clip, slide off the lever, and then take off the brackets for the cylinder. Then you can deal with the bolts and lock nuts on the bench.
