Pretty sure those are the opposite of what he needs. They are for using a push clutch with a pull transmission.

He wants to use a pull clutch with a push transmission, I think.

I don't think there is any solution for this - the push gearbox bellhousing doesnt have the place for the rod which the pull setup pivots on. If you have enough power to really need a pull clutch, then you should run a pull gearbox too.

Otherwise a HD push clutch with a heavier clamping pressure should suffice.
I believe it's quite easy to swap out your cable system for the hydraulic system if you want but this doesn't make the clutch itself work any better.
