Here are some photos of alignment adjuster sets from my front end repairs/alignment...

Left-to-right.... DJ Eberhart's set---Older replacement set that came with coach---Moog.

^^^^ Note that the OEM/DJ bolts are fine thread.

^^^You can see the radius on the DJ/OEM set vs the older replacement and the Moog set I initially bought, thinking that replacing old with new was a good thing. Note how much of the Moog set bolt was machined away to make the flat.

^^^ Here is the proper, longer nut that comes with DJ's set

^^^^^ These are the Moog adjusters shown on Amazon, and they appear to have the radius, but they arrived as shown above and below.

^^^ Here is the Moog set that stripped and deformed when I tightened it down to OEM torque specs.

The Moog adjuster is a punched flat plate without a radius on the inboard circumference. When tightened, the squared edge lands on the radius made when the flange of the alignment bracket was forged, rather than the face of the bracket. The OEM adjuster appears to be cast, and is radiussed so that the cam lays flat against that face.

DJ has an inventory of OEM cams that he uses for his sets. The bolts are new and machined to match OEM, and the nut is longer. This longer nut, beside being stronger, makes it easier to counterhold where it's behind the shock mount.

Alex Ferrara also made these sets; I'm not sure that he still does.

Terrific post, Bill, thanks!
 
This is great info. So were your old sets unsalvageable? Or was it just convenient to replace with new, and seemed like a good idea? I think I'll lean toward cleaning up my old ones when the time comes. It's good to know I can't trust the Moog ones, as I usually trust their stuff.
