Extended/long carb mixture screws?

Word is that they will be shipped to me in 2 weeks. Factory Pro is custom making them for our older carbs.
I have 2 pair coming. Looks like $30 for a pair. They include new springs and o-rings.

Ya know I saw them at the local CycleGear in stock for like $12 but I did not look what carbs they were for. They were very slick with numbers on the side. Might have been these ones http://www.cyclegear.com/eng/product/Air_Fuel_Mixture_Screw/web1008828
