Well, I am completely confused now. I called Proline today and asked them if the Bulldog B4.1 was the body that Cavo won the worlds with? The dude told me "no". I then asked if the same body will fit the 8mm longer chassis's? Again he said "no". I then asked if they have one that is for the new chassis mod, and you guessed it...NO. WTF is going on? Did people on this very forum tell me that their Bulldog B4.1 body's fit the chassis's perfectly? HELP !
