340 4 barrel automatic kickdown lever/rod

Thanks for the info, unfortunately, finding just that rod without having to purchase the whole set up seems to be near impossible. Anyone knows of one, please let me know. Have heard of plenty of guys on here modifying their 2bbl hardware by extending that rod. Was curious what issues they had

Just make one.

Put the rear tail "L" on the one you got. Steel 5/16" rod from the hardward store bend and weld parts together.
Don't have the skills or tools, visit your local iron fabriacator, friend with a welder, or auto body shop, and fabricate what you need.
