Fabricated the spacer for the upper spherical bearing, drilled out the top tapered hole in the upright, pressed the bearing into the arm, and it looks pretty good, just have to find a couple high-accuracy bolts.
Also, the bottom arm has been corrected; stiffening plates are yet to be added at the outboard end. The lower arm is now basically non-adjustable, but it’s not an issue since the upper arm’s used to set both camber and castor.
Since the bearings for the rocker arm’s haven’t shown up, I’ll probably build one upper and lower rear arms to see if there’s any issues there. But before that, since the coated turbine housing is back, I’ll probably fire up the engine just to hear how well the turbo and muffler work to quiet it down, and to hear, for the first time, the sound of the turbo whistling! 🙂
