By the way I don't want to make something that will just "work." I'll be driving this everyday as my daily, so it needs to be sturdy and super-reliable.
I had an idea similar to what you are thinking about doing LilPmpn. But I was going to build something with limitless travel. But I would loose the ability to make sharp turns. Not good for daily use. Ended up with just your average screw in balljoint.
Hey seth, were did you get the balljoint sleeves and the heims at. I would like to make a set of upper for my truck like that. With the screw adjustable instead of slots. Thanks
Balljoint sleeve is from Speedway Motors. I got the heims from Ballistic Fab. They are chromoly QA1 heims. They're not that bad a price. I also got the tube adapters there.
