i would say dont buy the aim ones. i havnt had them, and i dont know any1 that has, but i do hear alot of bad shit about aim. and another thing, you get what you pay for. my 2cents.
i would def go with jasons kit for the simple reason he will sell you the one door kit. no one else like to sell like that but he will break a kit up for no problem. well thats what he did for me a few years back
Hagan also has some nice hinges....spring loaded for a factory style opening door. they are more expensive however.......jason's are awesome as well. won't go wrong with either
