Between the actual TREs joints it's pretty parallel it seems in this picture.

Yeah but that's not mine

I don't think 1 degree of caster is enough, it will cause some of your symptoms.
You're saying you can't get 3 or 4?
Also what condition are your tires in?
So these cars never came with much caster. If I'm to believe the first alignment shop this went to, they said it was running negative caster. On stock suspension, most shoot for 1-1.5* positive. For the setup it has now I'm told 2* is good for manual steering. Power assist can get away with 3-4*. It can be a bitch to turn even at lower degrees, especially with the wider tires, but manageable.
Tires have about 4-5k miles on them. In good shape though these alignment screw-ups have scuffed them up a lot.
Today I switched out the center link as the '67 seems to have been updated from whatever year I had. It is tucked up higher and looks to move on a better plane. '67 is on the right. Pictures...

Old center link
'67
Idler arm is the same dimensionally
Idler mount is very different. 4 bolt closer together VS 3 bolts spaced farther apart. I like the current 3 bolt better.

This was all in the name of getting the tierods up higher and closer to parallel with the LCA. It will always be shitty since the pivots aren't in line and they aren't parallel.
Also grabbed some alignment shims. I have 3/8" behind the front arm bolts in an effort to add a bunch of caster, quickly, to test the theory everything is wrong because it needs more positive caster. BookFace isn't much help and Nova people kinda suck, but I'm willing to try.
Driver side will be Tuesday. The camber will probably be wrong now but good enough for a test once I shim the driver side.

The caster angles of those old cars was pretty bad but it had to be with manual steering still being pretty common. When I first got my 71 Monte Carlo it was pretty sketchy to drive on the freeway with the factory spec settings. I had the alignment shop set the caster as far as they could get it which got me maybe1.5 degrees total. It helped some. I've since replaced all the stock suspension with aftermarket and now have about 4.5-5 degrees and it's now really stable at speed.
