KZ250 Fuel Tank Question

Hey All,Pretty new to bike builds and just have a quick question hoping someone may be able to help. I recently brought a KZ250 1980 most all set up however notice a bubble on the fuel tank on the paint, long story short it was rust and had been fixed with a tank sealer however fuel was still escaping I pulled the paint off and quick fixed the leak with some tank putty sealer however have been on the hunt for a new tank. I've located one although it's for a z400d, looks to be similar shape but not sure of the fitting. Anyone know if this will just fit on without not much adjustment? Cheers. via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/bx01hq/kz250_fuel_tank_question/?utm_source=ifttt
