Major clutch/ throw out bearing problems.

About 6 months ago I had to replace the slave and master cylinder on my truck.after the install the truck wouldn't disengage the safety start switch on the clutch pedal or go into gear with the truck on. So what I ended up doing was pulling the pitman type arm on the clutch pedal off and adjusted it forward a notch. After that it would disengage the start switch and go into gear. But what I'm thinking is that maybe by adjusting it forward it's putting pressure on the clutch causing the throw out to constantly ride? Therefore causing it to wear real fast ? ...

That's the only way I can't think it could be something the pedal is causing.

Since adjusting that the throw out bearing has went 2x on the last 6 months.

It's a fine line on the position of the arm. You want basically no "free play" of the pedal when it is pressed (so no excess movement before hydraulic pressure starts and no "preload of hydraulic pressure). I know on mine I could feel it with my hand when cycling the pedal. Cheers!

Yea I'm gonna move it all back. Then check the bushings. I already did the heim joint mod. So I know there's no slop there

Pedal box bushings would be next on the suspect list. Quick-and-dirty test - rest your right foot lightly on the brake pedal, and work the clutch pedal with your left foot. If you feel any "feedback" under your right foot, the bushings are shot.

The FSM actually specifies that you replace the pivot arm every time you service the pedal, hydraulics, etc. This is because the splines on the shaft dig into the hole in the pivot, so you end up unable to make "fine" adjustments to the angle of the pivot after installing it once. I've gotten lucky and have found the right spot on both our trucks.

I have noticed that the brake pedal does indeed move even without testing it just noticed. But I'll replace those too. May as well
