Having had my lada steering arms messed up by another, any reason why I shouldn't make my own???

need more info i think...

If my memory is not letting me down(that would be the first time!)Rorty uses some U channel as steering arms and this worked good for him aldo he used them for off road buggy's though.

Have a ttached a pic of lada upright before cleaning...can see the steering arm there...any ideas...basically should I consider it or would it be risky, better to get old arm right.
the arms a re currently different lengths and heights, and taper the wrong way up. So do-able, by a pro of course, its all cast iron.

It will be cast steel not iron, very doable. The stresses are not great on the arms, should be equal to the stresses in your biceps, take a look at fiat panda arms. They are bolt on, can be turned upsidedown and (IMSMC) pressed steel

This is a reply I had direct from Rorty(posted with permission!):
