When replacing a Z's front frame rail, the T/C rod bracket needs to be separated from the rail so that it can later be welded to the replacement rail. The T/C rod bracket is secured to the OE rail by a combination of spot welds and a long seam weld. I'm looking for some guidance on the steps and tools that work best for separating the bracket from rail and whether this should be done before vs after the rail is separated from the rest of the vehicle structure. The brackets, BTW, used to be available as service parts (74830/78301-E4100) but are now shown as NLA on the Courtesy Nissan website.
