Fabing Trailing Arm ?

[tommypic]

I have looked thru the threads and was wanting to know if anyone has made or going to make a set of tube trailing arms . where they be square or round . my son works in a fab shop and he said that it wont be no problem to make em . I will need to get new bushings so he can make right size sleeve for them . just wanting any ideas that yall might have . cost is one reason I am thinking on going this route , put them $$$ some where else . I will just have to pay for materials . I think thats cheap enough .
