318 magnum EFI kickdown
The best way to swing this is to grab the factory cable, bracket and kick-down arm off a donor truck 88+, so everything stays the same ratio.
Don't bother with Lokar; most of the time you have to drill a hole inboard on the transmission arm. Not to mention you've gotta cobble up a bracket at the top, ugh. Top it off with the fact they don't give those Lokar cables away... My head hurts just thinking about it, if you can at all possible, just use the junkyard cable, please.
