Help; Headers for 4X4 with clutch linkage

[chevykevy]

I want to install headers on my 1969 4 wheel drive manual transmission truck. The clutch linkage goes from the frame to a ball mounted on the engine block just below the dip stick. I think the truck came with rams horn exhaust manifolds so they exit below the center two exhaust ports. I need headers that will allow me to run the Z-bar across from the frame to the engine. Any info or part numbers would be helpful. Pictures would be cool too. Thanks
