I have a 1956 Lincoln Premiere and am going to take off the holly inferno. I know there are issues with the dual vacuum advance on that year and upgrading to an Edelbrock.  Where would I find distributors that would work with that year? I know people have said go with a 57 or newer, but I am having a hell of a time finding a unit that will fit my car and work with the carb. hahaha Or is there a work around like a kit to change where the vacuum comes from? etc... I love the style of the car but just want a little more update in some of the mechanical. Thanks in advance to those that have something to share
