Hi all, I got a Do Santos DSMSCC RC in shop, the Spanish heel has failed , or rather collapsed into the soundboard, splitting it on both sides along the grain, a broken brace just under the fingerboard extension , cracks on both sides on the top/side bindings, I measured wood humidity on the fingerboard 9% and inside the (very inaccessible) body 11% The normal procedure would be to re-humidify before jacking or clamping back into place ,…

All - looking for recommendations on overall approach for repairing this nasty side crack right at the edge of the tail block. My initial thought is that either the top or the back needs to come off in order to properly glue and clamp the main split. Thanks in advance. Images
