Rear Sway Bar mount

Over the weekend I discovered that my right-rear sway bar mount broke off.

The sway bar is most certainly an aftermarket piece that the previous owner had installed. The lower anchoring point attaches to the locating plate for the spring leaf. I am including a picture for your benefit that shows the left side that is still intact.

It becomes clear that the locating plate has a "fifth" eye in addition to the four holes that exist for the large u-bolt that fixes the spring leaf. However, looking at the Moss catalog illustration the plate only shows four holes and does not depict the "eye". Nevertheless I don't think that the previous owner had welded this piece on either. Does anyone know what Moss part# to order that would allow me to re-attach it the way it was set up?

Obviously the rear sway bar mount looks a little like a make-shift contraption but I have not done my research yet on what alternatives/preferred mount points should be considered for the end of the sway bar. Any ideas?

Looks like a small piece of plate was bolted or welded on the u-bolt plate and the vertical pin from the rear bar goes thru a hole in that small plate. Inadaquate fabrication caused the failure.

What you want to do is redo the platform for the pin and bushing and add a welded perpendicular gusset to help support that platform.

If your serious you might also change the rubber bushings to at least hard plastic or better yet spherical rod ends and make the bar arms adjustable with a slider or multi holed bracket welded to the bar arms. At ride height you want the bar arms horizontal and no preload on the bar at ride height. If you stay with the pins, you want to shim the spacer length on the pin(s) to avoid preload.
