It's the other way around. After G-Force crashed their chassis at Spa, they didn't have one for Le Mans. So, to not miss the opportunity to race at Le Mans, Frank Hahn borrowed the Kruse chassis plus the people to set it up and entered it at Le Mans. I've got no idea what happened to Frank Hahn's chassis as it hasn't appeared at any other LMS race after Spa. The Kruse car belongs to Ian Mitchell.
