3846202 is a regular body bolt with a much smaller 3/4" conical washer and wouldn't be correct for 69. Definitely different to John Z's example.
The same bolt with a 1" captured conical washer would be AMK's B-12113 on pg 103.
The question from me is..
Does the 69 bolt have a captured washer and is the washer with this bolt flat? Conical washers are intended for more torque than a plastic shroud can take.
THe AIM indicates a # 120386 flat washer along with the #9419380 screw.
