I just installed a MiniDoMore hitch on my r53. It took about 45 minutes and was very easy. But... I can't seem to find a good way to put the pin in the hitch to secure the bike rack I'm using. I knew it'd be a pain, but I tried a couple different angles and couldn't get the bolt lined up. Any tips? Has anyone trimmed back the exhaust heat shield a bit? Would that help much? Thanks.
