GPX750 - Fuel Tank Gauge sender

Hi All
My GPX750 resurrection hit a snag on the weekend - got my lovely new tank back but discovered it has a six bolt fuel tank sender not a four bolt. Seems to have changed between years. Does anyone have one or know of any other models where there is cross compatibility?

Thank you, CMS were the only ones who had one. But at least I have a new unit for the new tank!
