G35 sedan w/ too much money in mods

That's a really good question. I would guess from Motordyne since those are proprietary items.

Added for future readers. :O

You can by the bolt kit from the MD site, which will include 6 plastic spacers. I'm willing to bet Tony will sell you just the plastic spacers though if you need them.

not sure if the OP or anyone else with this knowledge is still active.. but any chance we could extend this sticky to include bolt sizes for the exhaust too?

Unfortunately, I don't know the sizes of the stock exhaust bolts - perhaps someone else can post them up.

Bolts 1, 3, 6, & 9 = M6 x 1 x 60mm (red)
Bolts 2, 4, & 5 = M6 x 1 x 45mm (yellow)
Bolts 7, 8, 10, 11, 13 - 16, & 18 = M6 x 1 x 25mm (green)
Nuts 12 & 17 = M6 (green; these nuts & studs are sometimes replaced with M6 x 1 x 25mm bolts in aftermarket applications)

Intake Manifold Collector (Lower)

Bolts 1-6 = M6 x 1 x 70mm (blue)
Nuts 7 & 8 = M6 (violet)

hopefully this helps someone who wants to go back to stock, but has misplaced their OEM bolts.

Thank you sir!! This was super handy putting my 350z back together!
