Worked on Filtered Air Box. Got all measurements needed to put in the right spot. Drilled holes from carb mounting plate to VA-130B air box mounting plate. Fabricated VA-131-D filter retainers and installed with K1000-3 platenuts. Trimmed VA-130B to clear lower cowling. Put together ai box with the filter and drilled holes from the fiberglass airbox to the VA130B. Used lead pellet weights and worked from the back forward. Determined angle of the front of the top plate and cut out reliefs in order to bend it up accordingly.
