I have this same mount/antenna setup.
Did you grind both the top and bottom of the fire ring connection? Seemed to work better for me. Also, since the grounding strap is attached to the backing plate under the bumper area, you'll also have to remove some powder coat on a screw hole top surface of the mount (the inside beveled surface). This way, the screw itself will connect your ground to the chassis via the backing plate to the strap.
Fire ring-->bracket mount-->screw-->backing plate-->braided ground strap-->chassis
I think you're on the right track but there might be something minor preventing a good connection. I also used dielectric grease throughout.
Lastly, how/what did you do to run the coax to the front? Which route did you take? Do you have excess coax you had to coil up anywhere? Pinched/crimped coax at odd angles?
