Yes, it is tricky, so it requires some patience, but I wouldn't say "difficult." As I explained in the accompanying article, I keep handy a flat screwdriver to wedge the pads as far apart as possible during installation. I've probably spent as long as 10 minutes getting all to line up to slide the axle back in. It helps to get the wheel up on a 2x4 or something similar to get it at the correct height. I used to do this routinely with my '97 Blackbird XX, too. Picture sent to Fred.
