As a possible "solution" consider an alternative to the standard safety wire technique on this portion of the baffles. I got a couple of lengths of stainless welding rod, cut them to an appropriate length, threaded one end with a 4-40 die (dye?), and put a 90 degree bend about 1/2 inch long at the other end. Two small holes drilled through the tabs at the end of the curves on the lower baffles will let you feed the threaded end of the rod through from back baffle to front. The 90 degree bend acts as the stop on the aft end, while a 4-40 nut is the stop on the threaded end. Tighten the nut down until it holds the curves in their proper place and you are done. Aside from being adjustable, removable, and re-usable, you can also add one or two joggle bends in the rod as necessary so that it does not interfere with oil return lines or any other obstructions. Get the length and joggle bends correct on a practice piece, then copy to final rod and cut the threads. Works for me.
While not always available, I was able to find a 4-40 die at the hardware store that was sold as a single piece. Some stores seem to only sell dies in kits with many different sizes, and those can get a bit pricey.
