This is just for reference, I decided to install DM locking ring even my bolts did not back out. I also purchased OE flywheel bolts for $6+ per piece which i ended up returning because the ARP bolts fit the DM locking ring. I read that ARP will not fit the ring that's why i bought the OE bolts.

Here are the pics
OE vs ARP, ARP is longer
