you shouldnt need towers. in the pics it looks to me by the spacing of the arms it has the wide blocks on it. I have bought a few used vehicles and one thing ive learned is always take them completely apart and go through them. there are a lot of people out there who arent good at building these kits and build things wrong. the car will still work but not the way it was intended and you may end up being like this things a pos when in fact its something smalll and easy to fix.. thats the best advice i can give you. receive it and disassemble it. then enjoy
