welding question

Just my opinon but if your are asking questions like this then maybe you shouldn't be working on the suspension I would hate to read about you being in an accident controll arms are not that expensive as compared to a lot of other parts and building them can cause all kinds of problems if they are not done right. Try saving money on other things and then buy a set of controll arms from someone that has mfg. quility controll experinace also make sure they have product liability ins. If they have the ins then there product has more than likley been tested to meet the dot standards.

Not telling you what to do but that is one of those parts that can get you killed and I kinda like have all you guys around on this site.
