authentic or not it should be expected that there would be some work thats going to be done. just because its authentic it doesnt mean that it would fit like a glove. you guys have to understand that even the authentic ones came from a mold, there will be some imperfections on it no matter what. i had a minor fitment problem with mine and mines authentic but it was nothing any shop couldt fix. not once did i cry about it since i was expecting it already. the reason i went with authentic is because of fibergalss quality(how well it can withstand time) and not the fact that it would fit great.
my advice go with authentic but remember its expected not to fit
authentic will always be greater than any replica
btw i have heared that a shop around my area already made a replica(which i highly doubt since iam the only one here who has the kit
) but anyways i can always spot a vs replica from a mile away
authentic ones are 2 piece and replicas are molded as one piece so for those with replicas...i know who you are
