Check out the trim tag on this Z/28.

Nice looking car. Not sure about that short spoiler, though.

I had a couple of those 73 LT's back in the day, and I recall being able to order them with a Z driveline. I bought one brand new off the showroom floor, no spoilers or stripes/245HP/TH400/10-Bolt 3.73 Posi, and I recall the salesman telling it me the drivetrain was identical to the Z/28. He said it was a way to get the same car and pay less insurance. The second LT had stripes/spoilers/Saginaw wide ratio 4-speed that was a hoot to drive. If you put it next to a '73 "Z/28" and removed the emblems from both cars, the VIN was probably the only way you could tell them apart.
