Insert bushing begining in 200?

[Lacoutardes]

Hi guys.

I just bougth a Kubota B21 and I know I have to repair some Bushing on the loader arm.

But I don't know when Kubota begin to put insert in some location on their tractor, did you know?

Mine is 2001, so I hope it's with insert bushing, I wouldn't have the B21 until next weekend so I try to search about that.

Thanks for your help.

Sorry about some spelling mistake,
