Can someone help me with this. Looking into buying a73 z28. First off want to make sure it's real. 5th digit is a T and cowl tag indicates it's a z28. Owner advised me that it was an orig ac car and it came with a 400 trans. It was later converted to a 4spd M21. First off the air cleaner is a dual snorkel, and the ac line is now running behind the motor off of the compressor. Does this look right to you guys or do you think it had something to do with the auto to Manual conversion. Also paint is a non optional color for 73, and cowl tag indicates - - which meant a special order. I guess this one was a special order. Also, the grille is not black but rather silver. Any help is greatly appreciated.
