After breaking 4-5 droplinks on my '81, I had local racing shop
weld a bold onto the broken droplink.  This was their prefered
sol'n rather than drilling and tapping into the end of the broken
part.  I had them do two--so I'm ready if the other side breaks.

It has been installed ~2 years and I've given up that little
anxiety when driving over things that want to flex the body--
like gas station entrances.

I have put a scan of the repair on my web page:
