Pretty sure they are 4.5” BSFrom my research, they may be 4.25 or 4.5 depending on the year 80. Did you have some FZJ80 wheels on your 45 or did I see that somewhere else?? Thanks!

I have run them on the 45 before but I do have 1” spacers. Wasn’t sure how they’d fit in the 4Runner platform. They fit an IFS pickup.
Thought I ran them on the pig but maybe only sequoias wheels and the 17” allows them barely clears TRE
