yep, sort of past it. Because there was no markings and all was being put together "for the first time" I went with a 19° starting angle... there's no engine/transaxle/body installed so I'll see how it comes out and adjust splines from there. It is not exactly easy to shift one spline but I was able to do it to get them both at ≈19°.
One thing I noticed putting everything back together is that the left and right trailing arm bolt hole pattern to the spring plate do not match... there may very well be 2 different year/model arms on the car.. hard to explain without photo and I don't have photo of the "right" arm..
