Everything works fine independently.

The brake pedal swings free.

The clevis pivot is not binding and there are no weird angles.

I uninstalled the master cylinder, bench bled it again and it works like it should.

I took the booster off and depressed the plunger. It rebounds with no binding.

I made sure the plunger rod from the booster is properly seated in the booster.

Here are concerns
I bought a new firewall reinforcement plate/ clevis swivel kit and it was labeled (for mopar B and E body) but maybe not??

I'm going to install everything without the plate and see if I still have the binding. And if I do, I don't know what ima do!!

Suggestions appreciated !

thanks !
