Frank -
Sorry to hear of your installer issue. Especially now knowing that you could have handled it yourself with absolute ease.
I can tell all LOA'ers that this is a doable install (unless you need to drill your springs like Erick did then maybe not).
1. Do all of the messing around with the first StableLoad (SL) in figuring out how many spacer washers to use for your spring thickness, which side of the spring you want the SL mounted/hinged on, which of the 3 small grouped holes you want to use for your spring width, etc...
2. Then fully tighten the other 3 SL's in a comfortable place. After that those 3 will install very fast.
