Hey guys, I'm removing a solid mounted fan from a 351M and installing a thermal clutch and new clutch fan. The box for the clutch notes 5/16" - 18 x 5/8" bolts for the fan to the clutch, but I can't find this exact size anywhere. Checked lowes, home depot, advance auto and napa. Would 1/2" or 3/4" work just as well?
My other question is the bolts that connect the clutch to the water pump. Are the bolt sizes different from what was on the solid fan, length wise? Anyone know what size I should be using when I install the clutch? Can't seem to find it noted or listed anywhere. Thanks guys.
