74 dart sport 318 2 to 4 barrel

So I think I have everything figured out for the swap except for the kick down. Going with edelbrock performer intake and thunder series Avs carb. I saw the adapter from edelbrock for the throttle connection on the carb and plan on buying the larger throttle cable bracket for a four barrel. My concerns come with the kick down linkage. Edelbrock has a threaded adapter to lengthen the factory one but mine is solid and can’t unscrew for the adapter. Also noted that the 4 barrel throttle cable bracket I plan to purchase has provisions for the Lokar kickdown cable. Is this the easiest route? Thanks. Tried searching but couldn’t narrow it down. Thanks.
