welcome to the forum and congrats on purchase. it does look slightly bigger on the right side. will let more knowledgeable people opine but if nothing wasn't adjusted/repaired, I'd close my eyes and forget about it (after 1 year haha) 
No, you're absolutely right - it is. It's most noticeable if you look at the gap between your left inner and outer tail lights and those on the right - the space between them is smaller on the left than the right.Noticed after a wash can’t tell if it’s my eyes playing up but I swear the right boot gap gap is larger then the left
You rekon I should try and remove the right light and try and fit it again and hopefully should be more flush?There is a difference between left and right. The bottom of the left tail light lines up but the right doesn't. This is where the discrepancy is. It's marginal...but it's there IMO
