Thats what i was figuring, but when working with big trucks sometimes you use a weaker bolt to prevent more dnagerous or catastrophic damage to something else...just wanted to know i wasn't missing something.why not pay the extra dollar for insurance like that. i would definately go grade 8
I'd be scared of messing up the threads!some bolts like ARP require you to countersink the hole a little too for the bolt to seat.
It's not a big deal, in this case I was using ARP ring gear bolts for a 71 BB diff. The ARP bolts have a larger radius under the head and this required me to chamfer the hole so they would seat properly. Without doing this they might not be torqued correctly. Here is a hole I did before installing the bolts.I'd be scared of messing up the threads!
He was just showing an example of countersinking..come on, keep up...I hope you don't drive your vette this slow!!:spanked: :rolling:Did I miss something?? I thought we were looking at the bolts that hold the pressure plate to the flywheel. Now we're discussing a differential carrier?
