Yeah, I could probably weld a few patches over the holes in this firewall and go with the whole "rat rod" theme and I could even make the wiring work....some of those wires go to an old cruise control that is no longer there, others to a previous heater, electric fan, etc....The wires are all in decent shape even if they are not consistently color coded, etc however, since I have the engine out now and time is money, it seems like replacement becomes more cost effective in the long run and with fewer headaches. Besides, it'd sure be nice to trace down a wire that actually has it's function written on it every 6" and to open the hood and see a firewall that is smooth, clean & airtight!
