Hi Piet
I would buy that lower fairing.
Additionally, I have had two sets of stock Bayflex fairing extenders break on my Executive. I bought a set of fiberglass fairing extender replicas from Wolfgang and so poorly made that although I started the fitting process I have never got them to a point where I would consider using them. If your friend were to also make really nice fairing extension replicas I bet there would be a market for those, I would buy a set.
Alternatively, if anyone has a set of intact original Bayflex fairing extenders they would part with, let me know, I am your buyer.
