Toe In Angle of Boomerang Hub Carriers

[Juhunio 6887]

Does anyone know the number of toe-in degrees for the rear hub carriers on a Boomerang re-release? I've searched a lot and found references to them being "1 degree more" than other hubs, but nothing specific on their actual angle.

I'm trying to pick up some aluminium alternatives to the plastic kit parts. I've read others saying that the front knuckles could be replaced by TA01 parts, so I'm wondering if the same is true of the rears? There are parts out there with +0.5, +1, +2 deg of toe-in, but can't seem to find what the original Boomerang parts are.

Any help welcomed!
