The "repair" work took several hours and then I could finally get to work making it fit the car.
The filter base has a couple of carb adapters that can be moved to fit various carb spacing. They are tall enough to clear the choke horn on a Holley carb. I was able to cut about 3/4" off the height since the throttle bodies are flat on top. I dropped the base down to where I had just a little clearance for the throttle arm to swing.
