I need some locking nuts for the trottle bodies of the MFI system, engine 2,2S. The correct 999.084.601.02 are NLA. Can I use the PEL-WR-03680-8 Wurth Hardware: M8 Nylon Self-Locking Nuts instead? Do you know if these are yellow zinc coated? Would you use some liquid Moly Anti seize compound or Lobro Moly assembly lube on nuts like these?

thanks
John
