I would recommend replacing the tensioner rail because you are there and it's easy to replace. See my posting:

I took some pics and you may want to add to them or add you comments as well.

I suggest that you replace the rails first and check the offset, cam marks aligned and 'offset' noted on crank damper. If you do replace the timing chain, I recommend using a clamp on the drivers side sprocket as well. Get someone to help feed the chain in while you rotate the engine.
