If I remember right, the new street demon I bought came with a plate for either a spread or square bore.
One thing that truly sucks though, to put the holley mopar throttle arm on you have to dissemble the carb, maybe the new ones are different. A factory mopar throttle arm will not fit.
I even confirmed it with holley tech before tearing into it.
Not hard, but I could see a person not familiar with carbs having issues.
