Which Bolts for Crank Pully

[jhunte17]

I have a 1974 stock Bronco with original 302. It has been apart for several years and moved at least 4 times since being apart. With that said, nuts and bolts are no longer organized. I'm cleaning up engine pullies and have come to realize I'm unsure which bolts are used for the crank pulley. I took fairly detailed pictures of the engine but neglected to get a straight on shot of the crank pulley before removing. I think I have found the three bolts but they seem possibly too long.

Can anyone help me out with a picture or description/lengths?

Thanks

The stock crank pulley bolts have 6 notches in the heads and are recessed in the center of the head. They are an inch long. Most of the pulleys I have removed use no washers of any type under the heads. Lock washers tend to dig deep grooves in the pulleys around the bolt holes.

Thanks for the info. Those are the bolts I pulled out for this. I'm glad they're the right ones.
