Ok, I am now about to install my 4th "Wilwood type puller" slave cylinder. I have had two pusher types before.
I purchased my last one from Speedway motors

The price is right and the actuating bar is "peened" to the piston, so it can't unscrew like on the Wilwood.
This last go around the rear cap came unscrewed and fell off with the return spring.
I mount the "puller" the easy way not with a bracket like Cashburn. I leave off the rear shaft and run the actuating rod through the hole in the bell housing meant for the clutch cable. I think this mounting method subjects the slave to a lot of heat as it touches the bell housing and must pick up heat there, over and above what is gets from the headers.
I may try to make a bracket of some kind to mount the new cylinder and be sure to lock tight the rear cap. I will also put a short bolt in the rear cap and wire it to my frame so if it comes off I can put it back together.
I did buy two this time since the shipping was the same cost.
I did mention in a different thread that I re-routed my hydraulic line that used to run down the front of the foot box and very close to the headers. I had NAPA make up a line (rubber) that goes back from the clutch master on top of the foot box then down the side of the foot box to the slave. This keeps it far from the headers, but the fluid still gets black after a while. The problem with routing the line up over the foot box is that air gets trapped in the high point of the line. To bleed ,with out a power bleeder ,you have to disconnect the slave and hold it high above the master, bleed it then re-install.
Since my car is down till my new parts arrive I may take the line back to NAPPA and see if they can splice the line and install a bleeder at the high point.
If I come up with an easy and cheep way to mount my "puller" slave I will post it.
