Damn, I was doing good and was going to get it back together today. All cleaned up, put studs in, double nut, torqued to 15lbs... can't get the manifold on, it hits the frame. I got the studs from Napa, only ones they had in the size I needed, exact same length. The fine side is longer, which I thought would be good. Nope. Didn't realize how close it fits in there.
I need this exact stud:
3/8" X 1-9/16"L SS stud, Coarse side: 9/16"L, Fine side: 5/8"L.
Can anybody point me to a resto site that should have the right ones?
