Work on installing engine cooling baffles. P30-38 Aft Fence does not match the DWG, bends are incorrect. Contacted Sonex tech support, I have a new part but an old DWG. Thanks guys. New DWG does not have measurements for bends. Mark & bend P30-38 Aft Fence. Remove intake manifold & AeroCarb from engine. Install Aft Fence on engine.
