Door hinge bolts

[spongbob]

8750275 is listed as an "emergency" "Screw" as well as "Bolt" in my 86 Olds parts book. Not sure what that was supposed to mean, but it's not even a metric bolt. I'm not real sure about this one.

This is from the May, 1980 Olds parts manual showing the dimension of the bolt of 5/16"x18 x 1.125". Note that it is not metric. Several sources has this bolt, but usually it's labeled for the older A-bodies. But just looking at the listings and you could get confused. The Jan 72 shows an earlier bolt p/n of 7667647.
