which tank looks best on a 1978 cb750

[crxnug]

im looking for a new tank for my 78 cb750, im new to cafe racers and not sure which tank will fit without major modifications, does anyone have some pics of different tanks on the 750 so i can make a judgement on which way to go, any info would be a great help

I've seen a 400f tank on a 750 looking pretty good.

i saw somewhere but can find it where they said a suzuki tank looks really good, i dont remember the bike or year of tank?
