NV NOS Coolant Expansion Tank "Kit".

[71CHEVYSHORTBED402]

It's not a complete kit, but it's everything less a hose, pinch clamps and a retainer & screw for under the core support. The retainers are just nylon anyway. There are better options. Doesn't have mounting screws either. I used stainless steel rivet screws with K-nuts for a nice clean look.

Word is these were a RARE factory option, though govt. trucks had them down to the SPID. Other than that they were dealer options, probably varying on state regulations and/or climate. Before these tanks any overflow was released onto Earth.

Below is an image of the mounting instructions. I have a soft copy I can share. For what it's worth, I mounted one a bit differently, and I'm happy to explain how. Don't know if I agree with their top mounting hole location anyway (8.5/8" as I read it). Seems a bit high............................... $200 plus shipping, insurance & any Paypal to the first I'll take it. SOLD..................Yeah the tank holds water. Thank you.
