temperature sending unit

I have a 67, small block, with idiot lights and I wanted to replace my temperature sending unit (TSU). The TSU is the nail tip type, not the blade tip type, so I was looking in the Year One catalog and there it was, the picture showed exactly what I was looking for! YEAH! Its part # 3060N. I ordered it and soon it came. When I took it out of the box it was the wrong type, it was the type with the blade tip, and in the bag with it was a female adapter with a pin on the end. So I checked the part # on the bag and it was part # 3060N. I called Year One to report the mix up and they said "Well they dont make those anymore" I asked "then why is there a picture in the catalog?" They said bla bla bla bla........ So I am going to return it. Where can I find a nail type TSU the mounts in the intake manifold?
