Upper A arms for brake swap

If you have that goofy /6 k-member in that Barracuda- ditch it along the way. The idler arm is a 1-year only piece(available through such 'bargain' outlets as "Rare Parts"- an antique suspension parts manufacturer), only bolts in through the bottom. If you need a bunch of swap parts, hunt for a '73-up A-body(big-bolt pattern) for cheap. Buy it, strip it, and swap it over. You'll be dollars and headaches saved. Not to mention the fun you could have by getting shafted by a swap meet dude selling you common M-body suspension stuff as the now fairly rare A-body parts; the knuckles are abit taller on M-bodies and it'll fit it the A-bodies, but the geometry is abit off. Lotsa laughs if/when it breaks...
