It may sound strange, but putting washers under the spring pan on the opposite side front will cure it.
You may note that the passenger side front is now higher than the driver side? If you haven't noticed, go measure. .. get a stack of 3/8" id washers, some 3/8" all thread, and some nuts to fit. .. remove one of the spring pan bolts, replace it with the all thread, .. do that again and again until the spring pan is held on with nothing but your replacement all thread. .. go get some bolts about an inch longer than the ones you took out. .. take out one all thread, replace with the longer bolts but put a stack of 3/8 washers UNDER the spring pan. They're 1/8" thick, so using the measurement you took at the beginning you'll know how many to add. .. put it all back together the same way it came apart, except the the spacers, and you're lean will be gone, or un-noticeable anyway.
YMMV
