Not sure about the FZJ80.
But these ones are all the same.
The two bushes which mount to the diff that is (and rear arms).... its sized with a bolt hole 16mm and sleeve 50mm. Big outside diameter of 60mm and 40mm wide.
Don't replace with nolethane ones as they will not flex as much as the rubber and will tear out.
