The "crank it until it snaps off then back a quarter turn" is very old (and still good) humor, pretty sure I heard it first before these cars left the factory. The torque specs page from the library noted above is great, but does not contain the spec for the U bolts connecting the axle to the shock plate (leaf spring clamp). I have been Googling for a couple of hours now without success. If anyone knows what this should be it would be greatly appreciated.
