Now I'm done...at least with the suspension.
I had the Ol' Girl professionally aligned, today. As suspected, flipping the factory shims on the fronts gave me almost 3 degrees more castor, which put it within spec.
It's surprising that a few degrees makes a significant difference in handling. My old Jeep tracks and returns to center as well as my newish pickup, now.
With the new suspension, I can power over the washboard without the rear-end wanting to trade positions with the front. The wheel to road contact this setup allows is outstanding, especially for such a short wheelbased vehicle. I can confidently let go of the steering wheel on the straight away, which I've never been able to say.
She also brakes on a dead straight line.
The Ol' Girl will get her first big wheeling test when the elk-hunting season opens in a few weeks...I can't wait.
