Bought a new set of manifolds bit they didnt come with bolts. And i cant find anywhere which ones they are, anyone know the dimemsions?

 

I did a google search for "g37 exhaust manifold bolts" and this was the first hit:

Gotta love Google.

 

I got that too but it dosent give dimensions. And i already asked them and they said it would be 4 weeks for shipping and shipping costs more than the studs. Hence why i asked if anyone knew the dimensions.

 

Don't have the dimensions but maybe a dealer would? If you do some more digging you'll see this was the 6th search result:

Which shows OEM part # 14064-31U0C

A second google search of that part number brought these links:
