I have a 1979 F-350 4x4 that i put a 300six in with an Offenhauser 4 barrel intake I'm running a 4-2barrel adapter and a motorcraft 2 barrel what do i use for throttle linkage? Does anybody make a kit?

 

I just made up mine like this:

FORDMUSCLE webmagazine: Make Your Own Custom Throttle Linkage

Bought the parts from these folks:
McMaster-Carr

Another option is Lokar #DP-1000HT, but I think it is a little too $$$ for throttle linkage. All depends on your budget I guess.

Hope it helps. Good luck!
