Move upper arm mount rearward to allow caster adjustment

I know what I said. If you cannot understand I cannot help you. What I am talking about will result in zero binding, but give the same exact result as the offset bushings. You can beg to differ all you want. You're wrong. Keeping both bushing centers on the same plane and relocating the brackets would be a simple job. No binding, but just more caster. All that said, that's not how I would go about it anyway. I'd just get aftermarket control arms. Trust me. I understand the geometry. I did my first alignment in either late 1974 or early 1975.

offset bushings will bind though, how can they not, i think your confusing rubber compliance with zero binding.

as i said, change the rubber for anything harder and you have to have the bolts perfectly aligned. don't forget the bolts when adjusted stay in parallel with the chassis whereas the arm doesn't. Spherical joints would be the only way for zero binding with extreme adjustments.


but i'm also curios how cutting out the top arm mounts 'easily' and accurately then welding them back in 'easily' and accurately is actually easier than welding four holes shut and redrilling them in different positions?
