Oil pump for a Nuovo Falcone

Hi Gents
I am in the UK and looking for a new oil pump to fit my 72 Nuovo Falcone.
I understand that the T3 pump is better with more capacity and can be modified to fit by machining the mount bolts and modding the drive gear to a straight shaft instead of tapered. Bottom line is my request for a new T3 pump. Where is the best place t buy one? is there aT3 pump made by a good quality aftermarket supplier? Is there an upgrade pump available for a T3?

Thanks in advance
