What year are the FJ springs? If they are 2010 or newer there is some slight modification to getting them to fit . Search here or on google you should find something about it.
Hmm thats odd , i just put brand new fj springs from a 2013 fj and i didn't have any issues they fit right in fine! ill try to go out and check to see how mine are sitting,maybe i can get a quick pic.
Man look at that rust. You need to get out of the salt belt my friend.
It does help. The difference is mine are moog aftermarket fj springs and your are OEM take off. I got one spring to seat with a C Clamp and the other is defying physics and should slip in over night or maybe tomorrow when I take it around the neighborhood for a test drive.
