Tried scanning this post but I'm a bit confused on what body I need for a conversion...

I have a Losi 8ight 3.0 nitro and a conversion kit and I stupidly thought hey I'll just get the e 3.0 body however it appears that body is quite a bit slimmer so doesn't cover the plastic sides.

It seems people have been using a Proline Bulldog but I can only find this for a 8ight-e 2.0 body. Can anyone confirm if this will fit and also what other body options that would fit? The proline seems to be out of stock pretty much everywhere I look at least in the UK
