[89 KS notch]

I only put two in mine. The washers I found were extra thick. I think you should be fine. Do you have caster camber plates? I used an impact to tighten the ball joint nut and it's pretty tight. As tight as I felt comfortable making it. I have stripped those things out before so I didn't want to go that far. It almost takes two people to get those holes lined up. I couldn't imagine doing it without coilovers. How are you doing the rear?
