I would like the old ones that are being replaced to install new bushings in them. They do have to be the second design though. I have several of the earlier ones and the hole is oblong and no steel between the rubber and aluminum.
I used the one I bought from Barrett a few weeks ago when putting the '09 Uly back together. Found the original was torn apart pretty good, and figured it would fail at an inopportune time. Should last a long time with this brand new one! Thanks!
