I hope your primary is an easy fix. I remember on my 350 that the stud for the cover nut was just barely long enough and if I threaded it in to the case too much I could not even get the nut started, it kept me from overtightening it as I was always afraid of it pulling out.... Thanks for posting those fails and saves, great saves but man did it hurt to watch some of those fails, makes you really wonder about people sometimes.
