Hello All,

I removed my exhaust recently (in order to get the heat exchanger out) and found some bad corrosion on the bolts at the point where the exhaust meets the engine. 

I think these are 8mm x 1.25mm x 30mm bolts. Would it be ok to replace these with 8.8 zinc plated steel? (My uninformed guess as to what they are).

Thanks,

-Gavin
