Spaceliner "7" tank

[GuitarlCarl]

I know... hard to find part.
But I got a great deal on a red Spaceliner and it has the tabs for a 7 tank and according to the serial number gurus it should have the 7 tank. So I've always wanted a Spaceliner and now I have one mostly...lol. Can you guys help me?

Carl.

You can also use a girl's "tank" They are the same. The control unit on the back is different for boys and girls.
