Go for it
Ron,
I installed them on my -8A and found it easy to do. I didn't want to wait until after flying because I am trying to minimize the number of things that will take away from my flying time when it is done. Plus, I've heard from those that have done it that the gear feels more solid.
I cut out some base trim on a table saw per plans. You could probably cut it out with a circular saw if you had to. I glued the halves together, glued (epoxy and microballoons) them onto the gear leg and wrapped in 2 layers of 9 oz. glass cloth.
If you do do it, make sure that the stiffener is aligned (more or less) with the air stream. I roughly followed the gear fairing alignment procedure before installing the stiffeners to make sure that they would not interfere with the fairings once glued on. You don't have to get it perfect, just close enough.
