Sam, I have 90% of a NX kit laying around. I have both solenoids, lines, nozzle, window switch (DIS, MSD), a few Jeg's gauges, 5Lb bottle, 10Lb bottle. I have pretty much everything but I think the solenoid brackets. This stuff is all used and looks it, but all worked when it was removed. Both bottles are likely out of date, and I've stripped the paint off the 10Lb bottle to polish it, but that's as far as I've gotten.
I'll let this stuff go CHEAP. Make an offer.
