Dumb question:
I bought all new springs, hangers, U Bolts etc. for my Top Kick. I didn't get them installed right away. Now that they are on, inspection station says they are too short.

I contacted the place I bought them. They say "tough shi*"

I found a new source, bought new U bolts. I hoped I could jack it up enough to take the weight off the tires & change one u bolt at a time. I'm several revolutions backed off on the first U bolt, it's still very tight. How are these things done without losing your head?
