71 Chevelle Suspension install question/ UMI

[Bigwex]

Hey fellas! I finally had time to work on the car. I replaced the front upper and lower a arms with UMI (tall ball joints), UMI 2” lowering springs and tie rod adjusters. My question is, when I lower the front down I have crazy negative caster. Well that’s what I think. The top op the wheels point in an outward angle. I know I need to get an alignment but is it good to let the car settle and see what it does? I don’t have any shims in upper a arms and the factory units had two shims on either bolt. I just don’t want to screw it up as I won’t be getting an alignment for a bit. Thanks in advance! I’ll try and get pictures in a bit as well if anyone needs them.
