OK, maybe I've been out in the cold too long, but here goes...

'53 235 FP PG
Anybody know what size socket is correct for the head of the (6) flywheel to crank bolts?
5/8" (.625) too small
11/16" (.687) feels way too sloppy, and someone previously rounded the heads and it's making it difficult.

Question....could they possibly be 21/32" (.656) ??

FYI: The small bendable (safety) "lock tabs" are not engaged.
