Drop base 14 inch Air Cleaner

Adding an AirGap manifold has beaten me in the *** for hood clearence and I find myself in need of a drop base that will fit a Edelbrock carb with electric choke.
The drop needs to be close to 1 3/4 deep to make this work.
The Edelbrock drop base is only 1 1/8 deep which is not enough.
Anyone have any experience with this?
I ran a Moroso drop base on a Holley Strip Dominator with a 3" filter under a 73 Dart sport hood. The chrome "10 H.P. air cleaner"... Edit: Holley carb.
