Watched video. The installation is MUCH more difficult than imagined. While the installation of the boot to the inside drum is difficult, once the technique is mastered, it goes on somewhat easily, I used "Ruglyde", a commercially available slippery fluid used for mounting tires on wheels. But the three small rubber "clamps" used to hold the outer spring would not in any way hold the spring in place while getting it to go around the drum. I had to use C-clamps to hold the rubber clamps in place, in several positions around the drum, until it finally snapped into place. And during one try, the spring actually broke apart where it is attached together, requiring me to have to try to fix that by putting it back together and then crimping it so it would not come apart again. A very frustrating 3 hours. But I could do it again if I had to in 1/2 the time knowing how to do it.
