thanks - I suspect it is all "close enough" as if I measure the reamer and the Howe joint they aren't quite the same. Frankly I hate the tapered crap altogether and have been only running heims for some time now but I thought I would try to go with more off the shelf stuff on this car.

One thing I wanted to do was move the UBJ as well so I was pretty much always on a path to dump the stock upper - here is a shot of my dual A assy as of today - all the numbers are exactly what I want in terms of roll center, camber gain, and overall adjustability. I now have to fully adjustable pivot points (top and bottom) that I can mess with ride height and roll center pretty much at will.

For the Nova I am starting with a 13.5" lower arm length, 10.5" nominal upper length, and what both calculated in my computer and was verified with my angle finder in the attached image is a parallel lower arm nets me an 11 deg upper angle for a static RC of ~2.5" which is what I was shooting for. The lower pivot is not a ball joint but monoball from Coleman and they make a set of spacers that come with it. I can swap those around to vary the upper A angle and therefore static RC but comes with a 1:1 change in ride height (move the pin up 1/4" and the car drops 1/4") so if I need to make a big change I can then just buy a longer or shorter upper ball joint insert.
