I used the Van's fairings, but they are similar (probably not as nice as the RV bits version).
Photos of my installation here.
I had to trim them down a bit (got rid of the rough edges) and bonded them to the wheel pants.
Mike, very nice pictures and write up.. After a couple of years flying still no cracks?? By the way when you centered the "fairings" to the belly of the aircraft and wheel pant, did you have the wings on? Mark C.
It was a pain to install the wheel pants and gear leg fairings with the wings on. It'd be much easier to install them without the wings in the way.
