I'm putting a GT40 lower and Factory Cobra upper on my GT. I'm having trouble finding bolts for the upper because I got the intake free from a friend and it didn't come with bolts. I'm about to order a spacer kit, because it comes with new bolts. I got to reading on the Trickflow spacer and it says something about having to do hood modifications. I'm gonna get a 3/8 spacer, planning on getting the Mr. Gasket brand. Does anyone know if I'll be able to close the hood with this spacer on? Has anyone done this?
