atc 250r 1981 swing arm bushing

[quebecman]

Hi, I've got a atc 250r 1981 and I want to change the swing arm bearing. I buy the two bearings but I can't find the two bushing anywhere because they are discontinued (they made the interior of the needle bearing). Normaly, if the bearing are worn, i think this two bushing can be very worn. So I want to know if anybody here know a place that I can find that or the specification of this bushing (i'm machinist).

Thanks a lot :)
