Thank you very much for the info. I thought it seemed strange that they wanted to replace the entire arm. I know that Perrin at least offers both the 6 degree and 0 degree offset ones. I will have to research the AVO ones, I hadn't see them yet. It looked like getting the LCA's off was pretty easy on jack stands so hopefully I can find a shop that will do them while I wait.
My only concern from here is that the LCAs on the spec.B are different from the ones on the regular LGT and I wonder if there is a fitment issue?
