For me, by far its the damn brake booster. Everytime i remove that thing, i do not look forward to putting it back in! Ive found myself repainting it at least 3 times before putting it in without a scratch! Im making this post because i Just installed it and i am extremely stressed out and theres no beer left! Lol
