Your suggestion worked like a charm, Joel, as usual. I forgot that I spread the slots apart a little when I was taking the old ends out. And yep, I know it's not worth it to spend a lot of time on a makeshift alignment, especially with it on jack stands and no motor, but that one wheel was pretty bad. I think it would have been squealing if I had tried to drive it. I ended up adjusting both tie rods so that there is just a tiny bit of noticeable toe-in with the steering gear on center. It will probably change when it's on the ground with the motor in, but at least they're somewhat equal. I didn't mess with the shims - I'll let the professionals handle that.
And my steering wheel may be one or two splines off center - I'll adjust last when everything else is done if needed.
I think I now have a somewhat functional suspension, brakes and steering - who hoo! Just need one more small thing like a drive train.
