I'm almost finished rebuilding a G26 and the last project that should have been my first project is to rebuild the c/b. While trying to remove it, I removed the bolts on the bottom that hold in what I think are peices of angle iron and got them to vibrate if hit with a hammer so they are not rusted to the keel but the board still doesn't want to drop out of its spot. The c/b swings freely. Is there a through keel pin im missing or something of that sort?
