This is the window WINDER REGULATOR.. for the 70-81 Firebird TA & Camaro .. but ONLY with MANUAL WINDING WINDOW.. NOT ELECTRIC..
There is currently NO Electric regulators available.
These are brand new.
Choose the side needed.
They are OK for fitment to both standard trim and deluxe trim models from 70-81F series.
but the 70-72 std regulator used a 7/8" pin .. and the later was a 1 / 14/ shaft.
