darom Posted February 12, 2010 Share Posted February 12, 2010 I've searched here and googled' for the metric bolt size for a 280z intake manifold (stock 1976) bolt sizes, but in vain. There is a guy selling the 4-bolt kit on ebay for $20 (unfortunately he doesn't mention what size they are), but I can find the same bolts at the local bolt place for a cheaper price. Anybody knows the size, length? It looks like a 12mm, fine thread, 60mm long? Is this right? I've got the exhaust stud kit and gasket for the exhaust/intake job already. Thanks!

Administrators BRAAP Posted February 12, 2010 Administrators Share Posted February 12, 2010 10x1.25 2 of the 4 bolts might a little longer than other 2 as I have seen with some of the OE EFI intakes, (bosses are little thicker for 2 of the bolts).
