68 Dart Project.

not by personal experience but a friend's cross ram Duster lost a bolt into the engine. Not sure how his was put together but maybe the bolt itself was inferior material. I don't know if safety wiring them is a plan or not...guess that could mess up mixtures. From the looks of the picture, a plate over the top of the bolts would prevent them from being digested. Not sure how, I just have ideas...
