Need pic of 67 Z firewall

[iluv69s]

Hopefully I will be painting my 67 Z shortly. I realized that I have a few ´non-original´ holes in the firewall that id like to repair before paint. There is about a 3/4" extra? hole above where the column comes thru that I cannot find anywhere in the assembly manual. Also seems to be a few extra small drilled holes over near the wire loom and heater box area.

Does anyone have a pic of a correct original bare firewall they can post or email me?? My car is a basically no-option very late 67 Z. probably made the last day of production. 07C car

Any help would be greatly appreciated. Thanks SYC
