hurst vertical gate

Morning All,
I worked on these shifters for guy's a bunch 30 yrs ago. As They could not get them to shift right.They said "I used the pin like the directions said and they work great at the track but can't shift it at all on the street" What I found was One rod (I think 3-4) needed
to be turned 1 turn off of where the alighment pin put the levers. Then they shifted like butter on the street or when there was work to be done. Someone pointed out street shifting, palm up with thumb on top of handle then fingers under into gate rings or tee to downshift. Yes that worked great. They were easy to street drive that way. I just found a new old stock Large body Mr Gasket one for my 512" 69 Dart. Still in the box. Need to make up heim joint rods and a mounting plate now. But would need to do that with any shifter. As I am useing a 18 spline B body 833.
The question I have is? There seems to be 4 different versions of this shifter. 2 just pictured in this post. Mr Gasket small body, with T handle gate spring on the bottom back. Mr Gasket large body, with 2 ring gate rod with spring on rod and very heavy with straight rods. While the small body had bent stock style rods. Then Hurst had the same 2 versions also. I worked on them all for guy's 30 yrs ago but never gave it any thought.
You know just another job. I got them because word got around the Twin City's that I was the guy that could realy make them work slick. Does anyone know any history about these? When they are setup right there is nothing like them.
Take care,
Rick

Could you or someone else elaborate on setting these up with the "pin method"....ive heard someone else mention this before, but unfortunatly i dont have the original instructions for my mr gasket vertigate and i need something to go by when trying to adjust it
