Here's one of the upper bearing. It needs replaced for sure. Also as you can see, this shock is not equipped with the usuall rebound adjuster normally found on the 87up shocks. This is why I think it's an 86, but it looks to be in nice shape. Upon closer inspection I notice that the spring has been touched up with a yellow paint stick in a couple spots. Make offer on the shock. BTW stu, this was bolted on to my 88 when I bought it, so it should work on most quadracers. Do your homework to see if this hose will work for u. Make offer.
