I have this 4300D carb, P/N D3ZF-MA in my stock of spare 1973 Mustang parts. It has a vacuum actuator attached to the rear of the carb housing on the choke side that I can't identify (see photo). There is also an extra plate attached to the throttle mechanism (2nd photo - attached with two bolts) that doesn't show up in any shop manual or carb photos I have seen. Anyone have any idea what these are (California emission stuff, marine application?). The D3ZF-LA 4300D carb on my 4 speed Mach 1 does not have these parts.
