Super Six Air Cleaner

I did the super six conversion several years back on an '82 D150 'Miser'. One issue that's related to this thread is that, even though the air cleaner has the A/C compressor cutout, it doesn't quite clear the newer 6 cyl compressor they started using at some point. I need a 2-5/8" air cleaner riser, about 1/4"-1/2" tall. I only see 5-1/8" risers online.
Sorry that this isn't an A-body, but I thought it might be useful.
