So I took it back out to add brackets to both sides to allow shifting it a couple inches towards the driver's side to add a little more clearance next ti the passenger kick panel.
See how the back would slope away from the firewall? Added a bracket to the short bracket side to square the box up to the firewall. Have a little more room for the air ducts, Heater and AC Lines to be ran now.
This is before adding the extra brackets.
