So, I should probably update this thread. I've been busy with school for the past 3 months so I haven't been able to work on the car till last weekend where I was able to loosely put the entire suspension together.

Tonight, I asked my friend to help me real quick. I wanted another set of eyes when looking at my Dr Diff disc brake kit as I don't think anyone has installed this on an A-body. Apparently there were contact issues with some other rear mounted calipers and these UCA's due to an added bend in the UCA. Of course, mine interfered as my calipers are humungous. So, we swapped spindles side-to-side and there was a good 1-2" of room between the caliper and the strut rod throughout the suspension's full range of motion. So, some brake lines are going to need to be moved around, but that shouldn't be a major problem. While waiting and thinking for a bit we took a detour to install the driveshaft.

So, the project is moving along...
