D4B Hood Clearance?

One picture is my early attempt to stretch 2bbl kickdown rod. Others are factory 4 bbl linkage, on Offenhauser intake, and Holley Sniper. Note how the 4 bbl bell crank has different geometry.

Do you remember where you sourced the 4 bbl bell crank? It is the solution I am looking for. I have a factory 2 barrel car and B4D that I am considering using but do not want to make irreversible modifications. Thanks.
