Short of Grade 8 1/4-20 bolts and nuts so I made a run to the hardware store. Always a bit weary of hardware store stuff but the bolts are marked accordingly. Installed bolts, nuts and lock washers for sump to engine attachment. Torqued these bolts to 55-60 inch pounds.Switched to tightening upper engine mount bolts and installing lower bolts. Aligning the lower mount bolts is proving a bit challenging.
