69 camaro smooth firewall

[snappytravis]

So I am thinking about cutting complete firewall out, and installing bulkhead fitting for ac and heater lines on the rt side right below the fender bolt hole, and installing a steering column ball mount, then moving the wiper motor to under drivers side fender to hide, any good advice, I also will replace the floor around the transmission shifter so might as well do the firewall, would like pics if available thanks
