Yes these is the common combo with our East Bear kit.
Dimensionally it fits perfectly.
However the GTR and GTT run difference hinges, so either you need GTR hinges or what we do alternatively is modify the GTT hinge to work... quite easy. Weld a plate adjacent to the current hinge on the inner side and drill two new holes.
As with the catch, it needs to be brought forwards and up. Or alternatively use aerocatches.
