I bought a pair a number of years ago and now that I'm going through the build process, I was trying to install them. They don't fit will around the dash, the lower screw hole was at least 1" too high, the upper ends don't really fit well and need to be squeezed into place and held with the windshield or side window trim/screw. There was also a fair amount of trimming needed to get it to be reasonable. Does anyone make one that actually fits? Is there only one manufacturer?
