Used thin cardboard sections to layout templates for baffling around engine oil cooler. Middle section angle cuts to match top deck of engine block. Port and starboard pieces located step from VW engine deck to mounting flange step. Templates aligned together and traced on to a sheet of 0.025" 6061-T6.
Drilled relief holes for inside corner cuts. Used shears to cutout engine contour in Al sheet. Sanded and fiiled contour on bottom of baffle section across the oil cooler. Once the seal across the bottom didn't show an air gap, the starboard side was bent 90 degrees and the bottom and vertical step were filed to provide a similar light-tight seal.
Riveted a short angle to the starboard rear corner. Will set two #6 nutplates to engage the rear baffle.
