I'm not sure what you mean by connector bars, but the only things you need are the 410 grill itself, and either 410 headlight trim or the Samurai's that have been cut out from the original grill.... Hope this helps..
All Good Medicine,
Creator, everything we do leaves a track. May our tracks be ones we would want you to see and others to follow......
The connector bars(not sure of the exact name) are the two pieces of metal that attach both fenders top and bottom. I need these two pieces and I figured it might make the swap easier if I used them with the 410 grill.
