progressive linkage for a offy on a nailhead

Does anyone know of a progressive linkage setup for a 3x2 Offy intake on a nailhead that mounts above the throttle shafts?
I've got one for mine but the centre link hits on the intake directly below the carb.
i need one that would be above the throttle shaft not below it.
I did a search but couldn't come up with anything
Thanks for any ideas and thanks Rolf

I'm using a Speedway linkage with the same setup. Works good. Unfortunately,not a really good picture of it. 1-3 carb link goes high.

 

you have the same intake as I have but your throtle shafts look to be quite a bit longer.
I've got 3 of the Edelbrock 94's and the shaft is only about a inch long
that looks to be the reason. may have to look into getting longer shafts
update** your pic did help, did a search for throttle shaft extenders and the Hot Rod Company sells them! ordered 3 of them!
Thanks for helping

Yep - Speedway also sells the throttle shafts (oversize so you get a good fit)- as well as ****erflies to go along with them. Good Luck!
