Just got my first boot, for a 65 Malibu. Of course there are no instructions. The clips are L in appearance with the base of the L being crinkly. I am assumming the crinkly side goes over the chrome rail toward the inside of the vwhicle. It appears the flat part of the L tucks into a slit on the under side of the boot. Is this correct? The clips are two pieces, as they will slide apart. I have no idea why! But I assume they wouldn't mke it two piece for no reason. please someboby help! Thanks.
