Over the years, there were several different 2bbl carbs. What are their part numbers? The Autolite should have a small tag attached to the air horn with one of the screws, and the Holley should have a List number and a pert number stamped on the front, drivers side of the choke tower. Post all of the numbers, and I'll see what I can find out for you.
Take care,
