Fastzdriver Posted January 23, 2007 Share Posted January 23, 2007 I need to know what size nut the fits the studs on the stock 280z manifolds. Specifically the nuts that hold the downtube to the manifold. I need to purchase replacements to mount my new exhaust system and this is the last thing holding me up. Thanks in advance for the help guys. Quote Link to comment Share on other sites More sharing options...
