I looked up flywheel bolts for my build and i found this.....

there are two types of flywheels, one with 6 bolts and one with 8 bolts.....

this is the first time i've encounter this problem.
i have not check my obd2 b18b1 block yet but have anyone thought about this?

why are there two different bolt numbers?

reason im asking is because advance auto only have bolts in 6pc set and my lightweight flywheel is 8 bolt.... arp dont give a bolt numbers..
