I'm working on an early 3000 engine and have encountered these "special washers" for the 5/16" bolts on the timing chain cover.

There are 7 (2K5197) called for on the front cover but what is odd is that there are 2 different shapes. 

Normally I would conclude that they were from different suppliers but this is the 2nd time that I have come across this odd little detail on very original 6 cylinder engines, 5 of one type and 2 of the other.
Wondering if anyone else has noticed this and has a plausible explanation.
