What is the maximum amount I can lift the drive-train without a body lift? It seems that the tightest clearance is the top of the trans to the firewall/transmission tunnel. I plan to fab my own trans mount/skid plate. I have a cable transfer shifter, SYE, and adjustable rear CAs. Anyone have experience with a aftermarket lower clearance trans mount? If I don't even raise the drive-train a flat skid plate would be better.
