Finally, you could go back to scratch and consider changing the top mount so you can move the bottom mount. This then changes the force paths and hence you could redesign it to be stronger and lighter.

Spot on Treeve !!....We have all seen too many fabricated A arms of that nature, on all sorts of "Projects" - A simplistic solution that indicates lack of any engineering consideration, in so many ways. Would not be happy with something like this on my car !! Gregg.....It would not be too difficult to fabricate arms to do the job properly.
