We all have those days, just be carful around threads and aluminum, if it doesn't go in by hand find out why before putting a wrench on it. Take th 78 out for a ride and relax. I have been chasing a code 43 on my YT prioject since day one and its giving me fits, when I get frustrated I walk away and work on something else.
Hey Bud my Son still has a 66 Chevelle wagon I named "Christine" because everytime I would work on someone elses car it woukld break down afterwords, like a jealous women.
