Transmission linkage

Question for the guru's here. I have adapted a torque flight 727A to my 57 Dodge baby semi 325 and am using a Holborn look alike Fuel Injection EFI unit.

My question is: Any ideas on how to get or use linkages for the torque flight? I know that you have to have vacuum and the linkage set properly, or the torque flight will fry.

I'm thinking that many here that have gone with the 3G hemi and adapted a torque flight to it have had to rig up something like I'm talking about. Of course, that will be my next project with the Valiant. So any help would be appreciated.
