I used a pair of cutters to cut each tab at the openings of the bottom plate of the filter section. I left the side walls of the filter section on. Once the bottom id off the filter material just pulls out. This whole thing fits over the aftermarket air cleaner.
Put on the base of the oil bath. Install the crome air cleaner with a wing nut. The put the top section on over it and another wingnut to hold it. I meaured and there is an inch or two gap between the oil bath base and the bottom of the side wall of the filter section. It has given plenty of air flow. I thought that I might get a power shear and cut more of the side wall of the filter section away later, when I can make it a clean cut.
I could not figure a way to lift the flange around the edge of the lid and then make it flat again without dinging it all up.
