I know all cars seem to be a little different but I had to really beat the floor for clearance to get my CSI shield on a 904. My exhaust is super close to the pan ran and I can't see how a blanket would have worked well for me. My shield came with the mentioned 12 point bolts. I cut holes in the firewall to access them with a socket. I should have done that long before the shield, it sure shaves some time off a transmission removal.
