I have not even thought about how to deal with (or, without) the fender brace. I just removed it with the Rochester set-up. Maybe Sweet will remind us about how he did it.
I looked at my three trucks and their fender-to-firewall rods. The rods on each side are the same length and they attach symmetrically to the fenders/inner-fenders. However, I like Warren's idea about attaching the manifold-side rod one or two bolts rearwards (rather than bending the rod or eliminating the rod. I might have to cut and re-thread the rod but that is not a problem.
Here are some photos of the Carter-Weber "mock-up":
