5.9 Magnum engine timing cover swap

No, magnum bolts won't work with a LA cover. Got most my hardware from a hardware store. Grade 5 is more than sufficient. Just be aware that most bolts you buy from a hardware store come in 1/2" increments. Make sure that the bolts are threaded far enough so that they will draw up tight and not bottom out in a blind hole. I like to see about 3/4" of thread engagement.
