Phil: Check the glove box - they probably put them in there as spares
Art: Good catch. I had to have my axles alligned and the shop actually built new U bolts saying the old ones were 'stretched'. Regardless, they mounted them flush with the spring and even then they jacked up on them to 'mate' them with the spring surface. Told me it made a longer lasting contact point to reduce future torque changes. Now just over a year and no problems with them.
