I picked up 2 of the 18145HDs for my new 26mm bar. I noticed Paul F. had cut the end links down some to shorten them up. Why? Comparing them to the old ones, they are about 0.5" longer. Should I trim the spacer rod down some? BTW, the bushings are black on the end links. I bought them from Advance yesterday. Thanks, Scot 95 Red MTX - 66k Lewiston, NY
