I had the CSR full shield on the woman's car and it hit the seam where the firewall and tunnel are spot welded together. If you bend the flanges flat to the floorpan it will clear good. I got it to work without bending it but then the shifter cable was getting smashed and it shifted hard.
I finally on the last rebuild took off the shield and installed a blanket. Fits Great, shifts Great, works for tech, and all is Good.
Sorry I can't help you on that flywheel shield though.
Maybe it is hitting the flanges like mine did.
