69 barracuda with 73-76 sway bar end link mounts

hellwig 5906 76~72

i think this is your best course of action.

factory 73~76 doesn't fit unless you change the K out
factory 67~72 doesn't work with those tabs, so you'd have to weld on new or swap arms (expensive) and 67~72 bars are a little trickier to get
hotchkiss i don't think will work with those tabs and with their weld on tabs i think you might run into a logistics problem of too many tabs on the dancefloor.
