Replacing belt tensioner with Thump what idler to use

[tdotcv]

I changed the belt tensioner 2r3z-6b209-aa with the Thump belt tensioner. What smooth idler do you use on it. Lidio changed the smooth idler on original tensioner with a wider smooth idler. But that idler doesn't work on the thump tensioner that I want to use.

76mm and was it installed on a marauder before because I have to send mine back to get it re clocked so it sits in the right position.

Maybe I have to also use a thump pulley because the aftermarket one I have isn't compatible.
