Grade 8 bolts for engine to transmission - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Can I use grade 8 bolts for engine to transmission bellhousing? While installing new engine, two transmission bolts walked off. Presumably they are hanging out with one power steering bolt.
The car is 2011 SS and I thought about replacing all the transmission bolts. Those are $13 a piece. So I am wondering If I can just use grade 8 bolts.

They are a metric fastener so grade 5, 8 etc doesn't really apply. The metric equivalent of grade 8 is class 10.9.

OK thanks.
