Hello out there. This pertains to a Lund boat seat, where the bushing portion of the post is worn down from years of locking /unlocking/removal from the floor receiving "bucket". Is it just easier to replace the bushing (drill out rivet, re-rivet new bushing) or the entire post? If the entire post, does the shaft come out of the exterior post, and if so how? Sorry if this all sounds dumb, this is my first time doing this. Thank you in advance for replies or pointing me in the right direction. SS
