Hey fellas I'm currently working on a 74 gmc and I took it completely apart for restoration. I'm ready to start putting it back together and I needed the specs on the 6 bolts that hold the front cross member on the top rail and the 4 side bolts which r smaller. I'm replacing the hardware with grade 8 bolts as well. I'm not sure if that makes a difference, but thanks for any help thrown my way. Any info or pics that might need to b added for my reply just let me know and I'll get it for you thanks.
