Hurst does offer a reproduction round profile shifter handle with a bolt on provision for popular cars like late 60's GTO and 69 Camaro/Firebird.
They do not offer a reproduction of the 78-81 A body profile that I have seen.
So the car either has a non OEM handle or someone drilled the factory handle to bolt to the shifter; I have done this myself years ago with an ITM handle to a Competition Plus shifter. I have also seen guys damage the metal lock tabs on the factory shifter handle where the handle will no longer "lock" into the socket in the top of the mechanism. To rectify they will drill the shifter socket and handle to hold the handle in. There are already 2 dimples on the proper location to drill on the Hurst (the lower one on the ITM is too far down).
