One post is probably all you need. You are going to have a tough time finding one of those. There were no after market equivalent so people hung on to theirs. There was a factory recall for a Fuel Flange failure which replaced the top portion but that was years ago.
What's wrong with yours that you need a complete replacement?
I found a place that rebuilds the Vrod Fuel Sending Unit by getting rid of the electro plated sensor bar that always fails and replacing same with a more traditional float system. Did a great job for me. Was WAY cheaper than replacing the unit - if you are lucky enough to find a used one (forget about finding a new one).
Pulled my existing fuel sending unit (not that hard to do)...shipped.it to them and a couple weeks later I had it back.....WORKING!!!!
