136 tooth for the smaller metal only manually set tensioner.
137 for the larger plastic/metal auto-tensioner.
A lot of people say 136 is the better option because it's metal.
I went for the 137 as it has an auto tensionerit. Just bang an allen key in, turn it round till the marks align, and tighten up (still not easy with the amount of space available though!).
I think the 137 was fitted to later vehicles. Not sure when the changeover was though.
