When installing a trunk rack on your Vision...the trunk has a liner, on the lid, which must be removed for installation and drilling of the mounting holes. Here's a tip for laying out the holes. Use masking tap on the top of the lid to mark where the holes need to be drilled. When you drill the holes the masking tape also helps in making a clean hole. Be careful use a low speed drill and make pilot holes approximately 1/2 the side of the hole required. Measure twice, three times even four times to make sure the holes are lined up properly. The bolts go in on a slight angle so follow the manufacturers directions. They use a 1/4-20 bolt. I tried drilling a hole 9/32 but had to open it up to 5/16 as per manufacturers specifications.
