Is there a way to get stronger A arms for a 70 Olds 98?

I have had 2 break on me. I posted about it a couple of years ago. I
just thought Id send some feelers out there in case someone is
manufacturing them now. I have found some for 65-70Chevelles. I saw
some company that was making tubular A arms for those. Cant remember
the exact name...
