Temperature sensor / sender nut - where to buy?

I obtained a new old stock temperature sender off ebay. It fixes into the thermostat housing by means of a separate hollow nut/hex bolt with external M16 thread. The Nissan part number for the hollow nut seems to be 25251. I was going to use my existing nut to attach the new sender but found the the old broken sender is a different style with the thread being part of the sender unit. The nut costs approx £4 in usa but the postage is £14

Does anyone know anywhere that would sell a spare nut or a sender unit with the thread incorporated? I'm off to my local Nissan dealer tomorrow to see if they can supply (they were apparently also used on the 200sx) but do not hold out much hope

Thanks for taking the trouble to dig out the nut. Your picture shows two incompatible items' The brass sender on the left will screw directly into the housing and does the job. The brass sender on the earlier cars did not have a thread. It was the separate nut that provided the securing function. I might need that nut. However.....I have since ordered a sender unit with the thread incorporated. It is the same as yours shown in the picture but has a spade connector instead of a bullet connection at the end. Apparently this redesign was fitted to 280z and 280zx. I will try and post up a guide in a separate thread.
