Anybody know what size those 4 bolts are that connect front cat section to the lower exhaust manifold?
I know these show as a $pecial stud on the part diagram, I plan on replacing with stainless bolts, but they are so rusted I can't tell what size 'till
i start cutting etc.
Thanks,
Jim

I think they are a 16mm or 17mm, m10 stud. I just worked on them today, but i cant remember. I know it's an m10 from realoem
