I know this was not asked of me, however I just completed my upgrade with Moog parts Sunday from their problem solver line. They were well made and corrected all of the steering vibration that I still felt. The cost runs ~ 190.00 (little less) on Amazon. Of course if your a Prime member, no tax or shipping.
DS1430 - 85.79
DS1312 - 41.79
ES2079S - 12.28
ES3096L - 48.56 ( for qty. 2)
You are correct the Crown unit is ~ 20 bucks cheaper but I am not sure
@Jim King or I really have enough pavement time to know much about longevity, but I would expect them to install the same. I think the only unknown here would be the joints as I am certain you know. Also I had to paint everything except the sleeve. Not a problem just another step.
Give heed to
@JMT 's advice and lay out the new one against the old assembly as I found it to be solid advice when I reassembled mine.
