Check and see if you are using the inner holes on your shift levers (on the trans).
This will shorten the throw. It also makes the shifting a little stiffer.
You might look and see if the shifter can be aligned better on the trans.

To shorten the shifter throw on a Hurst setup you need to make a new hole between the existing rod hole and the pivot hole. The lever is hard, so you will need a solid carbide drill or mills. I have done this and it is possible.
The shifting will be harder since you are giving up some leverage. If you want to know how much shorter the throw will be you need to measure the current pivot to rod distance and ratio it to the new hole to pivot location. For example, if the current length is 100 mm and your new hole is planned to be at 80 mm, your lever throw will be reduced 20% and your lever force will go up 20%. I used mm since it makes the example easy to understand.

As pointed out they are hard (as in like a rock). It would be easier to get early C3 levers with the two holes in them.

I just finished installing a Hurst in my '73, and it works great now that I have tweaked it a little. I didn't need to shorten the throw to clear the plate, just had to move the holes in the mounting plate to rotate the shifter some and center it better in the plate. I also junked the shift lever that came with it in favor of the one Hurst sells for later models. This one is 1 1/2 inches shorter than the one for '69 to '78(?). The original Hurst lever was like driving a truck.
Also... I had a problem using the 'short throw' holes in the trans levers with my stock shifter. I got gear clash shifting from 2nd to 3rd and couldn't get the linkage adjusted to eliminate it. I was convinced it was a trans problem, but it went away when I went back to the long throw holes. Anyone ever heard of this???
