Took some time to figure out that what appeared to be missdrilled engine support brackets on the firewall are actualy OK. I was missing the floor beams that slide between the brackets and the angle. Also the lower corner hole that apears to be misdrilled is not a rivet hole. It is a tooling hole that is not fastened. Thanks to Glenn Mathis's web site for the clarification.
The bracket looks misdrilled
This is actually OK once the floor beam is slid into position
