Hi everybody, i rebuilt v6 99 and i broke this Bolt. I need the reference of this or a web site for buy. Thanks for your help.

 

main bearing cap bolts. should be torque to yield, gotta replace after each torque down.

 

Local chevy dealer, The only other place I would trust is ARP as long as they recommend their product for the application. Also If you buy GM follow the GM torque procedure if you buy ARP then use their procedure. As Craby said replace the set.. Torqued to yield bolts are tighten once then throw away but even if they where not TTY bolts and one broke all of the bolts have been through the same thing the other could have hair line crack that will give way under load and allow the main bearing to spin.
