ZEX Nitrous kit w/ New in Box Sparks barely used trades accepted

Will work with 2 valves with different fuel adapter. Got a ZEX kit with all necessary wires and hardware included. ONE HEAT RANGE COLDER SPARK PLUGS IN BOX INCLUDED. Comes with three switches. NOS purge solenoid (only needs tube or line to purge) and nx express bottle heater. Looking for 500 bucks or trades for aftermarket mustang gt 2005 3 valve parts or wheels. Im open to any trades/offers.
Overview:
ZEX Control Box
One heat range colder spark plugs, new in box(8)
Nitrous Fuel line
Nitrous 75 shot jets
Three Switches (Two toggle, one push button)
Fuel Lines
10lb bottle
bottle mounting brackets
nylon nitrous line brackets(didn't come with kit)
NOS brand purge solenoid(all it needs is a purge tube or line, has connector to fit the nitrous line)

BTW: If your installing yourself, I found that the hood latch firewall was the easiest to work with.

Nah I cant do it for 300, Ill keep it for three. I can do 4

I can part this kit out for more than 3
