Nothing about this car ever "just goes back together"; everything needs to be worked on in one way or another.

Front suspension is all together and steering is also. Hard lines are replaced, so I'm hoping nothing else about the brakes needs attention, other than new fluid and bleeding the system.

I think there's something different between the original upper control arms and the QA1 tubular arms, in addition to the geometry improvement they claim. I had my old UCA bumpers trimmed shorter to free up sime extension travel per feedback from John Calvert. With the same bumpers and the QA1 arms, the front suspension is completely topped out and the arms still have about a 3/8" air gap before touching the bumpers. I put in some taller bumpers that compress some at full extraction, but won't know anything else until the car is back together and I can check static ride height and available travel from that position.
