1970 Swinger 340 sending unit

This sender says it is built to OE specs? Did you notice if the wire wound resistor looked like an original sender? I wasted my time and money on a sender that was not. This may be a winner?
It has been a while since I purchased and installed it. I do seem to remember that it did look just like the OEM one, but I wouldn't swear to it. It works fine. It does have a fuel return nipple that will have to be blocked off for (I think) 70 and up.
