need to know how to look for a real abody 4 speed car

Factory 4 speed cars in '72 also had the reverse indicator light on the bottom of the dash just left of the ash tray a couple of inches.
If it is missing, then there should be a hole for it there.
If it was a 3 speed manual car, it would not have this light or hole either.............
Also, look in the driver's side fender opening behind the upper control arm towards the splash shield for the fender on the frame to see if the triangular shaped mount for the z bar stud is welded on there from the factory.
You can narrow it down from there to determine if it is indeed at least a manual transmission car..........
