Air cleaner option for QF 1250 dominator carb

[Adam68]

Hi All
I am looking for a air cleaner set up for the following set up
STD deck big block
Super victor milled down 1/4 inch to make it the same height as a Victor Jnr
MSD dizzy
It needs to fit under a 68 Camaro 2 inch cowl bonnet with the standard underside recess
I am going to call Universal Spinners tomorrow but there 2inch drop base set up but it is 16 inch and won't fit in the bonnet underside recess
I have thought about using a small 16 inch filter with their set up and them back to back with the top and bottom cut out a 14inch KN X top filter with the smallest 14 inch filter.
Does anybody know the approximate height from the bottom of the manifold to the underside of a 2 inch or another option that will work?
