So the engine's back in for some more mocking-up. I built these “thingies” out of 1/8" sheet metal, square tube, and random bolt/nuts. This is adjust the side-to-side movement of the engine more precisely. This is important when trying to dial in the crank to the car’s center line.
I was mislead. I have this "friend" that calls himself an engineer. He may very well be an engineer, but what lead me down this path of futility... He advised me to lower the steering rack independent of the lower control arm (LCA) mounting points, due to issues with roll center.
