What size Pipe do you run????

You can call Aircraft Spruce, they ship anywhere and are fair priced. It's easier to ship 3' lengths so buy a few of those instead of a long stick.

wat size for control arms? i was thinking 1.5x3/16. or would 1/8 work?

What are you building? 1.5" X .188 is huge for a minitruck, even big for a full size unless you are running the desert. I am running 1.25 X .120 (1/8") on the upper arms on the Mitsu I am building right now. I think it is bigger than needed, but it works for the size heim and bung I am using instead of a ball joint.

basically a mini lol. i was thinkin 1.5 was kinda big but i deffinately wanted to make sure,thanks for the help. now i can finally order the dom lol. what is good for the mounts? i dont mind using a basic poly bushing,but i was thinking about using heims. how well will that hold up?

Use chromoly, it's stronger and welds much nicer. You are only talking a couple dimes per foot more than DOM. Bushings are fine for frame pivots. On my Mazda I used 1" X .120, I would be using 1" again if I wasn't running a heim on the spindle pivot.
