Swaybar Tab location

I have a 67 barracuda with a 67 k member and am thinking of using factory tabbed '73 lower control arms for an aftermarket sway bar...is that a problem?
I haven't ordered the sway bar yet...perhaps I should just use my 67 lca's and weld on tabs...?
That doesn't work. Your pre 73 K member is closed cavity. The stabilizer bar routed around the front outside of it. Those OEM end link tabs were farther forward, closer to lower ball joint. Longer end link kits too.
Since the later model K was open cavity for stabilizer bar to route though the middle of it, the OEM end link tabs on those arms were closer to center of the arm and used shorter end links. So bottom line... No need to pay a higher price for late model lower arms that have the OEM end link tabs. Just ad tabs to the lower arms you have.
