I'm not installing a luggage rack but I'm doing a modification that if it turns out I'll post a picture. My question is when I look at a picture of the luggage rack it has two ears on it that attach under the seat and I assume screws are put thru the ears and threaded to the plate under the seat. I tried to install 1/8" aluminum plate into the plate under the seat. I beveled the screw holes so the screw heads are flush with the plate. My problem is that the screws thru the trunk do not line up with the seat brackets because of the 1/8 inch plate. How do they get around this problem using the luggage rack ?
