First of all let me say I have a sixth gen. Okay, here's my dilemma. I bought the 7th gen antenna mount and base and whatnot off someone parting out there Celica. I then bought an S2000 antenna. The reason I did this is because I didnt feel like hacking up my car to get the S2K antenna to work. And the 7th gen mount fits anyway. SO here's my problem: The antenna doesn't screw in! I'm worried that the base is the wrong year or model or something. It just won't screw in. They don't even look like they are supposed to fit. Should I have the power antenna or non-power antenna? Does it matter?
