My comments, for what they're worth. You should consider the condition of the chain along with the corresponding gear sprockets as a unit system - you're looking for excessive slack in the combination of the chain and gears. Examine the gear teeth for wear on the drive-side of the teeth. There is a kind of "rule of thumb" for chains; when removed if you can easily squeeze in the center and bring the two sides together for anything other than perhaps a very small amount of contact, chain replacement is indicated. There are other similar tests, like sidewise twisting or holding horizontally and judging the "sag", again to make a judgement of the amount of wear in the links and pins.

And you also have to consider whether modern repro parts are of adequate quality to warrant the replacement of serviceable original parts. I bring this up only because, while it's wonderful to have some of the repro parts we can get today to keep our cars on the road, they are not necessarily a match in quality for the OEM parts.
