Steel trailingarm reinforcement?

[safe]

I'm thinking that I might need to reinforce the trailing arms on my -69, they look a little wimpy....
As I gather the -73 RS had strengthened trailing arms. Anyone have ides or pictures on what could be done, aluminum arms that don't fit my budget right now.

There is a lot of info from Neunelfer about reinforcing the steel arms in this thread (yes I realize the title does not reflect this).

Swap steel trailing arms with alu trailing arms?

Thanks, that was exactly what I was looking for!!
