When building clones for a dual quad set-up for 58 Vette 245 hp, I believe the following parts are need for the conversion: throttle levers, choke cover (and housing threaded),air/fuel mixture screws, and jetting & metering rods. Also, filling holes for the choke removal on one of the carbs. Are there any other parts or procedures necessary to create the proper cosmetic and functional outcome? Thanks.
