Did you (or anyone out there) have any better installation instructions using the existing base? Mine has cracked too and I see from the internet others have had a similar issue just trying to get the thing installed. Any suggestions would help. Thanks.
Well, I have a confession. I won't go into the details of why this happened but I have installed the standard dynon static ports with the flange pro sealed to the exterior. So at this point I two questions.
1) other than it being a "total drag" is there any reason why they can't be left that...
