I checked out Poly Performance. I didn't like their
track bar bracket. It looks like it mounts higher and further to the right than stock, and is made for rod ends. It also does not provide a place for a steering stabilizer.
I found
these at Dynatrac. Looks like stock replacements, but thicker. I wonder how difficult to make them fit my D30 or since they seem to be for their larger D44 tubes.
