As far as I know, ALL Panteras can use the same sender and float regardless of year. Practically any FIAT, Alfa or other such car dealers sell an identical float- I'd look for one from the early '70s to be sure. All the vendors likely have them but with such a small, cheap part, its not economical to advertise them. You'll actually have to call & talk to one or more. Junkyards sometimes don't even charge for floats; bring a set of small metric sockets.
