Clutch adjustment question

[sr71mopar]

Its a 66 Satellite 383/a833. Did not run when we got it. We had the flywheel turned and put in a new parts store clutch kit. Stock style B&B.
The problem is, when you press the clutch to the floor, something is rubbing on the clutch hub coil springs. I can see the rub marks with a flashlight. I'm assuming its the fingers on the pressure plate. When I back the adjustment off to eliminate the interference, the clutch pedal does not come back to the top. It's down a couple inches and is below the brake pedal. The over center spring is in place and everything moves smoothly.
This is my first mopar with a clutch, but this does not seem right. Any ideas?

Did you remember to mount the return spring on the clutch arm? I removed my over-center spring because I was using a diaphragm pressure plate. The pressure of that return spring alone is enough to bring my pedal back to home position.

When I set mine up, I was advised set it up so home position, with pedal up at top of stroke, the throw-out bearing was about 1/16th - 1/8th off the fingers of the pressure plate diaphragm. That way I'm not touching and burning out my throw-out bearing, and I should still have enough throw to completely disengage the clutch.

All the measurements boil down to 1" of pedal free play before clutch disengagement. The overtop spring works within that 1" to pop the pedal back up and keep the throwout bearing off the clutch. When depressing the clutch it then acts as a "helper" with the Borg and Beck style clutches but is not necessary with the diaphram style clutches.

As for the marks of the springs, its very likely the rubbing is the fingers as you suspect - duo to one of two things ... 1) the disk is installed backwards or 2) the clutch is not adjusted properly allowing the fingers to be depressed too far. The disk should have been marked "flywheel side".

The disc is in the correct way. The return spring is in place. Its almost like there is too much travel at the clutch fork compared the pedal. With an inch of free play it needs a 2x4 under the pedal to stop it from hitting. I'm starting to wonder if it has the wrong z bar.

Verify you have the correct parts. Check for lost motion through the entire setup. Check to make sure the fork is all the way onto the pivot and the release bearing pads top and bottom.
If your plate finger backsides are running into your hub springs you're adjusted in too far. Plate departure is about .060" to start.
IMO, it's better to adjust into it rather than adjust back to it as it is possible to damage the fingers if they bottom out.
FWIW..........

wrong z-bar or wrong clutch fork. I'm not sure if the z-bar can be installed backwards (end for end).
