I'm trying to find bushings for the seat base plates for my 89 Ranger 373V. It's got the round 9" plates with 2" holes. I'm assuming that I've seen some base plates listed for a 1.77" pole that must be it. I can only find bushings for 2 3/8 or 2 7/8 or something like that and not the 1.77" I'm assuming that must be a rare size. Is there any other choice than buying more base plates and taking the bushings out and trashing the plates? I'd hate to pay 25-30 bucks a bushing though.
