I'll try to get a picture posted, but in the meantime I'll describe how I set them up. Not quite OE, but it seems to be working well enough.
I ran the fuel line in steel from the fuel pump, behind the engine, up across the top of the cable bracket and then down to the front carb inlet (with short hose connecting the pump and carb). I made supports at the cable bracket and at one of the bellhousing nuts. The carb to carb run was also down with bent steel tubing with short connecting hose. The OE routing is right across the front of the filters, which seemed odd to me (especially given the fancy filters Robyn got) so I ran them under the filters.
For the linkage, I routed the cable across the engine in the same manner as the OE Z-S (not sure if the Weber cable can be modified) using the stop bracket from the Z-S manifold. Take a look at the linkage lever between the carbs - the part the cable attaches to. The linkage on the carbs when we got them was too long to allow the cable to pull the throttle plates much past 1/2 open. I ended up digging up a linkage set at Carlisle that moved more for a given pull of cable.
