Front towing D-rings. Cab11/12? Bolts securing bumper

[Alex van de Wetering]

Guys, does anyone have a picture of the bolt that secures the D-rings and bumper to the cast front spring hanger on a C8?
Even though the cast piece in the front differs from C15, C60 etc., the parts catalogue seems to suggest the bolts used to secure the D-rings are the same throughout the series. The partnumber is "1799028" "Bolt, front towing clevis bracket".

All 8 bolts on my chassis were cut a long time ago. I am trying to determine what thread size and measurements the proper bolts have. As the hex head is quite large and the holes in the casting rather small, I presume the bolt could have a slightly larger diameter boss to fit the larger holes in the bumper???
