Trunk Separator Panel
I'm considering adding a trunk separator panel to my 1970 Mustang coupe, both to increase torsional stiffness and to reduce the chance of fiery death in the event of a rear-end collision. I figure I'll just take a flat piece of metal and cut it into shape.
I've seen both aluminum held in with sheetmetal screws, and steel welded in. I imagine welded-in steel would do significantly more to increase torsional rigidity, but would be much harder to remove in the future. For anyone who's welded in a "trunk firewall," was rear shock nut access a problem afterwards? My interior is still out at the moment, so welding is not a problem.
