Drop base for a 750 dual feed double pumper

I have a beautiful spun aluminum aircleaner, with a beautiful reverse-velocity stack lid, with 2.5/3" drop.
It's sitting on a shelf instead of being used , cause the drop is so extreme that it won't clear throttle linkages, or fuel line connections.
Be careful what you ask for.
I'd look for the drop base with that has a designed-in clearance for cathedral bowls on a holley. Pontiac ram airs used one, so did L88 corvette, and they are being reproduced/copied.
