As with the right side, the left side angle iron mounts to the two M8 holes provided on the oil pan to mount the lower fairing.
The oil pan on the left side of the motorcycle has a protrusion caused by the oil filter bay. So, to make the angle iron fit correctly, you need to place a couple of spacers between the angle iron and oil pan holes. On mine, I found some M10 nuts that were of the correct thickness to serve as a pacer. I silver soldered the nuts to the back side of the angle iron so that they would be a permanent fixture on the jig. I used a M8 clearance drill to make sure that the actual mounting bolts would be a slip-through fit.
