Looking to stretch my assault 146 to 153. What am i all going to need? track drivers and rails?

So you don't want my 146 cobra track? Why 153? 155?? Rail Ext., Tunnel Ext., and track. Drivers depending on track choice. I"m thinking about doing the same thing to mine!

You won't need a tunnel extension.
