Reinforcing The Subframe of a 107

[Philoprof]

As the 107 subframe problem was already discussed here, I was wondering if someone would be kind enough to tell me the best way to go about reinforcing the subframe of my 380sl at this point. I've read about a repair kit with brackets/gussets that can be welded onto the subframe, but I haven't found that kit listed anywhere on the net.

Thanks very much for any advice.
