With all the things that have been changed on this vehicle, you really shouldn't be having problems with the clutch slipping. The only two suggestions i would make to you, is that the flywheel may have been machined past the point where it is too thin or that there is something contaminating the clutch material.
What does the clutch pedal feel like? Does it engage more towards the top of the travel, or seem to be more towards the bottom of the pedal travel?

It is more towards the bottom. There is no oil coming out of either the transmission or the rear main.

It;s very possible the previously machined flywheel is the culprit here. Nothing regarding the hydraulic portion of the system should cause the clutch to slip. Both the low clutch pedal and slipping points towards the friction parts.
You're going to have to take things apart again regardless to correct the problem, i'm going to suggest removing and inspecting the flywheel, see what the surface looks like. Best bet to replace it. While your in there, you can double check the throwout bearing and any moving parts for binding/sticking. Just for good measure.
