I pieced together my own replacements for my RD bars from rod-ends from www.racerpartswholesale.com
along with a stud bar (for joining the endlinks) and a female connector piece (not sure what it's called). I picked up those extra parts from Brofasco, but I think HD sells the same stuff for much cheaper. I also had to enlarge the holes in my OE hardware because the bolt diameters were slightly different.
I had been running without my rear bar for 2 years because of the worn out endlinks. I finally got around to doing this project this spring and it's been running perfectly quiet since.
