I pmed sparkbr a while back and havent heard from him...
I'd really like to get my hands on a quality set of these, but I feel like it'll take a lot of fabrication on my part, because they have to be specifically made for your boat. I got a dvd and some info from beavertail, but I fail to see how they can just sell pods over the counter without knowing the angle of your transom and the bottom of your boat..
