Pulley dimentions

Hi guys,
you all have been a great help with getting me sorted with my sn92 charger,

Im having to get a pulley made for it though as my bottom pulley is 6.75" i need a 5" charger pulley to keep things safe and not over rev it.

i am wondering if someone could measure up a pulley if they have one spare, like length of the main pulley shaft, from where it butts up to the front of the charger to where the securing bolt and washer touch overal size of the pulley shaft,
hole size in middle of shaft, (cant measure my charger as its not here)
and if theres a step on the front and rear of the pulley where it conects to the main shaft,

im going to have the pulley made to the same spec as a factory pulley if possible offset etc, then if the bottom pulley ever gets changed to a different size i maybe able to use an off the shelf paxton pulley to get the rpm correct again without having to get another charger pulley made.

thanks again,
