Which L bracket? Note the bracket for the cable housing is separate from the adjacent one anchoring the return spring. Looks like the Mazda pickup linkage kit now provides the latter as a straight piece with large (bolt-down) and small (spring anchor) holes, rather than having that dogleg bend in the middle, but should work about the same either way. Or you could probably just make your own with a strip of sheet steel in a bench vise to form the bends.
