I just bought a new 2 door JK and now comes the fun part... Buying new parts. I have a good sized budget but being the way that I am, I'd rather save a few here so I can buy more stuff later. My question is what are the major parts of the JK that are compatible with prior year JKs and which years. ie. soft top is compatible with JKs from 20??-20??, doors are compatible with JKs from 20??-20??. I am looking 2012 specific. Thanks for the knowledge in advance.
