On my 85 CVX18 the rear flotation is long gone and the ventilation consists of the open vents, no hoses and a blower just pulling air from the open void on the starboard side. I have sourced the original collector boxes and installed them but where in the upright partitions by the engine should I punch 3 holes and route the hoses? Low as possible on both sides? High on port side ( intake hose) low on starboard ( blower suction) side?
Thanks
