You're welcome to order both types from us and return the kit you don't need.
Our kits use top-quality parts, and the Cambelt Tensioner we supply is an all-metal item that is very hard to find (most have a plastic wheel) - to our knowledge all the options regarding suppliers you have mentioned use plastic.
We have everything you'll need here:
