I'm not entirely sure that I understand your question, but I'll give it a shot.
I think perhaps some clarification in terminology is needed here. If you're talking about the piece that fastens to the shifter body and comes up through the rubber boot in the floor, I have always known that to be referred to as the "shift lever". The only "handle" I know of related to a shifter is a "T-handle" which sometimes took the place of the round knob on the upper end of the shift lever. Hurst did manufacture T-handles which fit their own shifters. There were numerous other types, too.
To the best of my knowledge, the '66 and '67 Chevelles all came with round, chrome plated shift levers, with a round ball on the end. They also had a sliding bushing just under the knob which had two finger pulls on it. You had to pull up on this bushing in order to engage reverse. So if Hurst is manufacturing something square with the word "HURST" imprinted on it, I don't think it's a repro for '66 or '67 Chevelles.
On the other hand, if someone is reproducing an original-appearing round chrome lever which can bolt onto a Hurst shifter body, I haven't seen or heard of it.
