The linkage direction is correct on a DGV, it is just the mounting hardware for the part of the cable that doesn't move can be tricky. On the stock carb, the cable jacket bolts right to a bracket on the carb, but the weber has no such mounting. The full kit for a LUV comes with a bracket, but I've heard it is less that optimal. (Never had one in my hand to say for sure)
I believe a DFEV would have the linkage set up for a cable pulling from the passenger side, which would be backwards from the stock carb. Routing a cable like that would take some creativity I'm sure. I could be wrong on exactly how the DGEV/DFEV differ though as it is hard to tell for sure from the diagrams I found at
