Cafe racer tank

[suzukix7]

Hi guys,
A long shot I know but does anyone know where I could get or a tank I could use for my TS150 café racer project?
I'm after something that is longer and lower than my standard tank. The problem is that the frame on my TS projects upwards quite sharply where the tank fits.
If anyone knows what other people use or have any suggestions then please let me know.

Regards Dave
