I need two exhaust manifold bolts, the ones that bolt the manifold to the block. I'm missing two and would like to have a set of replacements available before I try to get the remaining old ones out. Does anyone know what the specs of that bolt are?

Thanks!

 

Anyone?

 

They are 5/16-18 if anyone was wondering....

 

I don't know how I missed this thread, but yeah, that's what they are.
