Subframe connectors

Had rusted front floor pans, so at the same time of the forward floor repair, cut the rear pan and slipped in 2x3 tubing 3 inches into the rear frame and a couple of inches into the forward frame, welded entire length. I do not sit in the back so do not notice the small hump in the rear carpet! drilled hole in tubing for parking brake cable and gave me a secure place to attach rear battery cable. noticeable improvement in handling.
