intro and lowering my 4` coupe

[1980gold]

So I took the car out on the highway yesterday It does fine up till about 50 and then starts to wanna go to the left. I know I need shocks all around in a bad way. I was gonna check the king pins for wobble on my next day off. Also does anyone know if my tie rod ends are 11/16 or 5/8" threads. theyre cheap enough and I figure it could only help to replace them. thanks
