Hurst shifters

Thanks "jimharvard", Some very good information here..
One question I have is that on the OEM Hurst shifter. The reverse shifter fork does not have a alignment hole in it. Is there a "trick" that is used to hold it in the neutral position when adjusting the rods?

i once had a conversation with a fellow street racer about adjusting his OEM shifter and he said he put the shifter on a bench, lined up all three forks and then drilled a small (like 1/8th or smaller) hole through the reverse fork into the next fork. he then put a cotter key or bolt in the hole when he was installing the shifter rods. it sounded like a reasonable "fix" to me...
