Thank you Smallfoot. I seem to get as much out of building as driving, maybe more, so it's hard to stay arrogant about my building if I keep screwing it up. The fenders look good until you get close-up.
I have been re-clocking the pinion shaft angle slowly, so I redid it again this year, because it isn't good enough yet. At high-way speed there is still a fine vibration. There is now, two, four degree wedges in under the springs. I've been having troubles finding flat surfaces that are parallel to the appropriate shafts to get good readings on shaft angles. Compounding the troubles is the fact that I don't have a hoist yet, so I have to do all of this measuring and changing while lying on my back, using only one arm jambed under the frame, and using only one eye,[jambed under the frame] and that eye is now vertical instead of horizontal. My horizontal stabilizer level doesn't work very well when I'm using only one eye, and it's vertical. Life's a bitch, sometimes, right?
Once you get that many wedges under the spring, the centre bolt head is too short to reach down into the spring perch hole, so you have to weld an extention on each one, to keep your rear-end straight under your truck, [think dogtracking].
