The Tonti tanks will fit various other models with exception. They will not just drop into place with out adding or taking away something. Along with a way to secure them to the frame.
The Leman's tank is mounted in two different configurations. One uses two tabs at the front of the tank that go under studs on the steering neck. One uses pockets in the tunnel that slide over rubber bumpers on the frame. The back part has two types of mounting points. One used a rubber strap, one used a screw.
The same goes for the SP and T style tanks.
Then you have the seat/tank relationship. The Leman's had two types of seating positions. One has a high back section of the seat with the front of the tank sitting higher than the back. The other model had the tank more level and the seat more level. While the seat and tanks look the same on both bikes, they are fitted together different and mounted different.
I mounted the older tank with the newer seat. I had to use a heat gun to reshape the seat pan to match the frame and fit the back of the tank.
