Ok so we’re getting ready to put the replacement engine in my 2001 2500HD 6.0 and one of the exhaust bolts was broken of like they do. So we removed all the bolts and are going to replace them.
So my question is where should I get the new bolts GM replacements or get them from somewhere else and use stainless or grade 10.9.
And do we use anti-seize or not?
