I just bought a 95 gt 3 weeks ago. I thought it had a vacuum leak and it does. For some reason the bolts that bolt the egr to the tb/intake were loose. Well actually the top bolt was completely missing and the bottom was loose with the gasket hanging out. The bottom bolt that was in it is a 8mmx1.25, but it wont tighten up like it should in either of the bolt holes. It has a 65mm tb and a cobra intake. Does anyone know what size it should be?? i have tried a bunch of standard bolts, but it must be metric. Any help is appreciated!!
