Need a Trackmaster 'Arry chassis.

Sorry if I'm posting this in the wrong chat. I'm using this for the first time haha.

A little while ago I found a Mattel Trackmaster 'Arry shell in the grass. I took it home with me because I don't own 'Arry (don't worry I cleaned it). Sadly I don't have a chassis for him. I've heard the TOMY chassis's don't fit them so it has to be a Mattel one.

If anyone could perhaps help me out I would really appreciate it!
