When we pull the belts tight to lock them in place we want a little counter tension on the tensioners. Tighten the tensioner knob a few turns until the tensioner looks similar to this.

It is not advised to use the belt lockers that come in the metal kit. They are beta parts but the preferred way is zip-ties

Pull the belts through the front plate so they're tight. I used a few drops of superglue on the smooth side of the belt.

I clamped the belt to the 2020 to give the glue time to dry.

Remove the clamps after 5 minutes. Tighten the zip-ties and cut off the tail and the extra belt length.
