Looks nice. I have to do the same job on my JD 450 one of these days, but I guess it's not quite that bad yet. The bushings are mostly gone on mine, but the pins aren't sticking clear out of the links and riding the sprocket like in your old rail pics. I guess that's a wear measurement to shoot for!
I bought mine with the intention of doing some clearing and making some new roads on my farm, then selling it. Well you can probably guess where that plan went. I'm just about done with the roads and clearing, but I don' t know how I could ever part with it now.
