MEP-002a & MEP-003a Head Bolts

[rustystud]

Does anyone know what the physical dimensions of the head bolts are on the MEP-002a and MEP-003a generators ? The one I know is 3/8"-16 X 1.75" . The other one is not listed in the parts manual, just the part number.
Thanks.

the other head bolts are 4.25". 4.25" tends to be kinda hard to find but 4.5" does work. the head bolts are grade 9. here are the mcmaster #'s for both bolts and the thick washers.
