Remember if you get the tubing the ID is going have to be smaller than .75 and 1.25, i believe youll need something like 1.185 for the lowers to have them tapped and probably about .685 for the uppers if you choose to go that route. Jim Reep of Reep Machining is very very good, that is who does most of my heavy machining that i cant do. If you have the rod end properly welded though it should never ever come out, i tig them and rosette in 2 places. If you think that stuff is overkill you dont even want to know what i use for arms, if you havent bought tubing yet i can get it to you way cheaper than anyone, whether its control arm or roll cage stuff. Call Jim and see what he can do for you 704 944 8325, tell him Alex told you to call.
