• Type 3
• Stainless steel ARP bolts, washers and 12 point nuts
• Special alloy, ‘300 series’ ARP stainless with a tensile strength of 170,000 psi
• Substantial extra margin of safety over Grade 8 hardware
• Polished to a high luster
• cNw modifies these bolts to ensure exact fit for both cradle and Iso mount
• Available for both Pre MkIII and MkIII engines
• If you are looking for the best possible hardware available, then this is it

Note:  One small modification is needed to install this bolt kit. A relief needs to be cut on the cases (see images) and a Dremel tool or similar can be used. This by the upper, right side of the front Iso mount.  A ball end cutter will work the best to remove just enough material so a wrench will fit over the 12 point nut so it can be held securely as the bolt gets tightened. There is a chance that you can grind a wrench down really thin so that it will slip in over the nut but the relief is most likely necessary
