TAZ!! has old jib car tracks which are recessed in the middle (not flat like newer ones). I am not ready to install new tracks yet. The pins (screw down or spring loaded) on the new cars are not long enough to span the recess and secure the car on the tracks. Does anyone know where I can get a couple of spare cars? Mine are showing some wear and tear and I'd like a couple of spares. They don't have to have blocks on them but they do need to have a means for attaching blocks.

Thanks
