Alright when I bought my 86 awhile back the PO decided he wanted the firewall shaved and took out all the ac stuff and welded plates of metal and then covered the welds with fiber filler well I want to put ac back in it so I need pics of the firewall with everything removed and if possible measurements from side to side top to bottom and so forth heres what im dealing with

 

The welding looks nasty

 

Yea its horrible one of the reasons I want to put ac back in it
