Could be the wrong idler arm, it's what came on the car when I got it 2 years back. The alignment was awful when I first drove the car home, could be an indicator that the arms are wrong? It seems kind of weird to me that I've got a '73 car and the pre-'73 mounts so I wouldn't be surprised if I have the wrong idler arm. I'll try to get a picture and measurements to check.
I've got new torsion bars on the way and just put in new shocks so we'll see if that does anything to help. It's got the biscuit style mounts and I've already got 3 thick washers under the passenger side, but it still rubs.
