['68OrangeSunshine]

I suggest modifying the '68 accelerator push rod set up to '72 style cable throttle. I ran the old push/pull rod for a long time but it was cr@ppy. Linkages came loose, small bits fell off, it even iced up once in the mountains. Too much of a Rube Goldberg. I changed to a cable and it was never smoother. And you can mount your carb in any orientation you want.
This is the cable I used. A GM cable/gas pedal assembly off a '71/'72 truck was used in the cab.
I used a Jeg's throttle return spring to retract the spring on the engine side. [A big screendoor spring to the brake master cylinder was ruled out as too Retro-Jethro].
