PO replaced the kingpins not long before being put out to pasture. The front end is sound as a cat, no play, no wander, no slop. I guess I incorrectly stated that after I re-read my post. When I said bushings, I was meaning to say all the front end rubber, such as what sits in/over/around the idler arms, shock arm mounts, etc.
All mine is badly weathered, and while everything is sound for the most part, I would like to replace to give a uniform look. Parts may be unavailable, and I'd just have to deal with that.
