The Guppy Attack antenna will fit inside of the OEM Antenna Mast Base, with some minor trimming, allowing you to use the OEM part, and OEM rubber antenna gasket. Here are the parts you need:
1. OEM Antenna Base, you can reuse the one from your OEM antenna, or order one from Acura, PN 39156-SL0-013, it's about $3- and includes a new rubber gasket.
2. Dremel tool with Cut Off Disc, I prefer to use a new cut off disc for a clean cut.
3. Eye Protection, since you're cutting into ABS plastic, it can clump and fly off, I strongly suggest eye protection.
Remove the rubber gasket from the OEM Mast Base, then cut off the part which sticks below the flange, here:
Reinstall the Rubber Gasket, to create this:
This part replaces the swivel base of the Guppy Attack. Here's a comparison between a Modified Guppy Attack on the Left, and a Standard Guppy Attack on the Right:
With the Modified Base it's even more critical to ensure everything lines up; perfectly aligned you will get about 2 turns on the top 19mm nut. Take the extra five minutes to make everything precise, and you get to look at a perfectly aligned antenna everytime you go out to your car. Installed Pic:
