I'm trying to remove the lowers from the uppers on an '02 MXR 29er fork. There are 15mm nuts on the bottom of each leg. Problem is that one of the legs has the rebound adjuster rod that runs through the 15mm nut to the bottom of the lower leg. It's probably 3 inches long (from bottom of stancion to bottom of lower. I can't find a socket that long. Any ideas how to get to that 15mm nut?
