Having done it I can say the only benefit to getting one at the pnp is to get experience taking it apart. I think the liklihood of getting one that will work is less than 50/50 unless it is from a really clean vehicle that met a sudden and unfortunate end. Be aware that wagons and sedans had different speedos, the sedan is designated by k9800 and I forget what the wagon is. The margin of difference I was told when I did it is negligible. I personally feel purchasing the gear is a time and cost effective way since you will probably pay as much for a questionable instrument cluster as you will for a new gear. Of course there is always the chance that the little silver motor is bad, as was the case w/ me which is why I ended up putting my new gear in a k9800 cluster. That, I am told, is rare. Before removing the cluster, have a pad and pen handy and write down or draw a diagram and note the color of the wires that are attached to the cluster, including the terminals that are unused. Of course, three of the connections have unique shapes and only go in one location. Note that there may be an unused yellow or orange wire behind the cluster - just ignore it, which makes a good case for writing down the color and location as you detach the wires. The most important part about the gear replacement process, if you go that route, is to support the cluster in such a way as to avoid damaging the needle on the guages. Oh, and don't drive without the cluster. The charging circuit is broken and you will run your battery down PDQ.
