Anybody know what size the exhaust manifold bolt is on 1999 Chevy Silverado 1500 Z-71 5.3 L . It appears that my front driver's side head broke off, I need to quiet the truck back down. It's not leaking bad at the moment, but I know it won't stay this way..


Any suggestions on what brand, arp, etc to replace these with.. ??

thanks,


brian

 

Really the GM ones are pretty good. I'd get a new set from GM. All the LSX series use same bolts I believe, double check though.
