questions about super six conversion

hey, ya i recently bought a super six 2 barrel manifold and carb set up and i will be switching it onto a '68 slant six with a 1 barrel. I have read some of the other posts and i see that i need a new kickdown and throttle linkage. i was wondeing were i could get that from and if it is just a stright swap with the 1 barrel stuff?
