Bob,
From my collection of what used to be 4 hoods and several fenders, there were subtle differences between them.� Maybe the parts were drilled during the stamping process. Maybe the holes were added after assembly. I really don't know, but having a set match after the body parts are attached to the jeep would make sense.
I ended up using the hood holes as a guide and moved the fender holes to be right below (only needed on one fender).
I wonder if getting a consensus on hole locations would get you "in the ball park" on location?� I wouldn't be surprised to hear some measurements matching. I have a 3B but will measure and add if you think it will help.
