Rich,
Screw 3847757 had a serrated flat washer while the later 3847758 was the same, but NO serrated flat washer. Bet GM had a slipping problem with the later bolt (758) so went back to (757) serrated. (But who knows?)

Also see Section 11-13 Sheet B7.00 / Think LI has these

Alan,

Screw 3847757 must have had a running change somewhere in 64-65. I know that 68-up headlight actuator rod bolts use this part # and they have a non serrated washer. Also the 67-68-69-up front and rear seat mount bolts use this part # and they also are flat washers.

So now the question is when did the change to the washer take place. I know from most of the bolts that had serrated washers the main useage was for 63 and 64.
