I messed around with this all day yesterday, mostly because I had no idea on any mount depth issues.
From the pictures you can see that it's about 1/2" out. I've ordered ring spacers to fill. I had a shallow mount kenwood in there before.
Space is tight, the pioneer needs about 7.75 or so...
I am driving into an incredible deal on some FZJ80 3rd row leather seats on craigslist from a 1997 FZJ80, curiously, will they directly mount into an 1991 FJ80?
I apologize if this has been asked already.
I included an image of the seats for reference.
