List, For what it's worth, I found the following torque specs for US 5/16" (approx. 8mm) and 3/8" (approx. 10mm) bolts: Grade 5: 14 lb-ft and 26 lb-ft Grade 8: 26 lb-ft and 37 lb-ft It would seem reasonable to me that the values for the MG rocker pedestal bolts would lie between these values. Certainly (?) they wouldn't exceed grade 8, would they? Ed Woods
