hi looks like you guys are doing a great job! and good luck!..but...not to complicate things for you, that "trough" above the upper control arm is one of the (few) weak spots on an Eagle. There is no drain, so water, salt crud, etc, just sits there until it eats through. I just went through this with my 84. there was a rust hole less than the diameter of a quarter, but, it was all the way through. Long story short, the whole framerail was rusted out, from the INSIDE, with very little indication from the outside. I had it fixed, (not cheap) and to prevent this in the future, I had the outer "lip" cut off, so water can drain. good luck, gz
