Honda 1500 vents March 26 2015
Some aftermarket vents have the same hole pattern as the Honda 1500 vents. The holes are smaller and closer together. This would require using a dremmel tool to lengthen the two outside holes to accept the mount. However its come to my attention that the 1500 vent's attachment at the top is not as stable as the 1800 Hondaline vent. I would suggest that if you wish to use the EZ-GPSMount you upgrade to the 1800 vent. The hole size for the 1800 vent is larger than the 1500 vent so the windshield will have to be modified to fit the 1800 vent. This will provide you with the best possible performance from your EZ-GPSMount.
